2.2.1 Why?

The rOpenSci website has a page listing all authors who have contributed to a blog post, tech note, or presented in a Community Call. A click on your by-line in a post takes the reader to your author page that has links to your online home, possibly your Twitter or GitHub profile(s), and a list of all the content you’ve authored on our site. For staff and leadership team members, editors for software peer review, or members of our Code of Conduct Committee, their rOpenSci title is also listed on their author page.

2.2.2 How?

If you don’t already have an author page, create a folder called yourfirstname-yourlastname in your local copy of roweb3/content/author/. You can have accents, middle initials, or hyphens appear in your name if you name your folder appropriately. That can be tricky so we have examples below.

In that folder, create a file called _index.md with information about your online presence. You can copy this template below (or get it via roblog after installing it via install.packages("roblog", repos = "https://dev.ropensci.org") ).

---
name: Author Name
link: website URL or other online presence
twitter: Twitter username
github: GitHub username
gitlab: GitLab username
keybase: Keybase ID
orcid: ORCID ID
---

At minimum, provide your name and a link or your Twitter, GitHub, or GitLab username. Add your usernames or ID’s without the “@” or the “https:…”. The link field can be your personal website URL, for example.

2.2.3 Examples

This author file, /author/kelly-obriant/_index.md

---
name: Kelly O'Briant
link: https://kellobri.github.io/
twitter: kellrstats
github: kellobri
---

… generates Kelly O’Briant’s author page

This author file, /author/maëlle-salmon/_index.md

---
name: Maëlle Salmon
twitter: ma_salmon
bio: rOpenSci Research Software Engineer, Associate editor of rOpenSci Software Peer Review
github: maelle
gitlab: maelle
keybase: maelle_salmon
orcid: 0000-0002-2815-0399
---

… generates Maëlle Salmon’s author page.

For an example of how to name the folder with an accent and initials, see this author file that generates Richèl J.C. Bilderbeek’s author page. The folder name must include accents, initials with periods, and hyphens for spaces, in order to link to their blog content.

Look at other people’s folder names for examples.

2.3.1 New Post Addin

The blogdown New Post RStudio addin creates the post draft in the correct location and fills the post YAML based on metadata you’ll have entered.¹

• Install whoami (install.packages("whoami")), and blogdown above version 1.1.10 (at the moment of writing, only available from GitHub, so remotes::install_github("rstudio/blogdown")).
• Install Hugo (to preview the post): blogdown::install_hugo().
• Re-start R.
• In RStudio, open the forked roweb3 project.
• Create a new post by running Addins > New Post or blogdown:::new_post_addin().
• Leave “Categories” blank.

• Enter a title, no need to worry about title case at this stage.
• Enter your name if whoami wasn’t able to guess it.
• Choose the correct date.
• Enter a new slug if the default one is too long.
• Choose “blog” as a Subdirectory from the drop-down menu.
• Choose an Archetype, Rmd or md, from the drop-down menu.
• Also choose the correct Format: .Rmd if Rmd, Markdown (.md) if md. Never choose .RMarkdown.
• Ignore Categories.
• Select “tech notes” tag if this is a tech note
• Select any other relevant tags and/or create new ones
• Click on “Done”, your post draft will have been created and opened.

2.3.2 Manually

Create a folder YYYY-MM-DD-slug/ (e.g. 2020-01-20-rorcid/) under /content/blog/ Your post source and its images should live in /content/blog/YYYY-MM-DD-slug/.²

• R Markdown template is to be saved as /content/blog/YYYY-MM-DD-slug/index.Rmd. It will need to be knit (RStudio knit button, or rmarkdown::render(<path_to_file>)). Add both index.Rmd and index.mdto your PR.

• Markdown template is to be saved as /content/blog/YYYY-MM-DD-slug/index.md.

2.4.1 YAML

The YAML sets the metadata for a post. This is the YAML from our post template, with comments to explain some components:

---
slug: "post-template"
title: Post Title in Title Case
# Delete the package_version line below if your post is not about a package
package_version: 0.1.0
author:
  - Author Name1
  - Author Name2
# Set the date below to the publication date of your post
date: 2020-03-10
# Minimal tags for a post about a community-contributed package 
# that has passed software peer review are listed below
# Consult the Technical Guidelines for information on choosing tags
tags:
  - Software Peer Review
  - packages
  - R
  - community
# The summary below will be used by e.g. Twitter cards
description: "A very short summary of your post (~ 100 characters)"
# If you have no preferred image for Twitter cards,
# delete the twitterImg and twitterAlt lines below 
# - Replace "blog" with "technotes" as needed
# - Note "/" between year/month/day
twitterImg: blog/2019/06/04/post-template/name-of-image.png
twitterAlt: "Alternative description of the image"
# the text below is for populating the "share on Twitter" button
# if deleted, the title of the post will be used
tweet: "A post about blabla by @username!"
---

2.4.2 External images

If your blog post has any images that are not generated from R Markdown, put them in the same folder as your post source (/content/blog/YYYY-MM-DD-slug/). All non-R Markdown images should be in this folder (do not link to external services like imgur). To reference them in your post, use name-of-image.png. If your image is e.g. an hex logo, it might look better with a transparent background because the blog background is not exactly white.

Every image should be accompanied by alternative text (alt="informative description") to make it more accessible to people with disabilities and provide a better user experience for everyone. The alternative text should convey the meaning or content that is displayed in the image. Refer to this tutorial for details on what should go in alternative text.

If you want to generate images from R Markdown use our R Markdown template and see next subsection.

Insert an image

• Insert an image with either figure or imgtxt short codes
  • {{< figure src = "image-name.png" alt = "informative description" >}}
  • {{< imgtxt src = "image-name.png" alt = "informative description">}} Text to right {{< /imgtxt >}}

Image placement

• Basic positioning with {{< figure >}} and class

  {{< figure src = "image-name.png" alt = "informative description" class = "center" >}}

  • pull-left - Left-align the picture and wrap text around it
  • center - Center the picture (no text wrapping)
  • pull-right - Right-align the picture and wrap text around it

• Specific text next to image with {{< imgtxt >}}

  {{< imgtxt src = "image-name.png">}} Text to right {{</ imgtxt >}} Text below

  • Only text between {{< imgtxt >}} and {{</ imgtxt >}} is to the right of the figure

• For images side-by-side, create a composite and insert as a single image
  • Consider gimp for free and open source image manipulation software
  • Consider the R package patchwork for combining R figures

Other details

• Control image size with width
{{< figure src = "image-name.png" width = "400" alt = "informative description">}}

• Make the image a hyperlink with link
{{< figure src = "image-name.png" alt = "informative description" link = "http://hyperlink">}}

• For very large images, consider image compression such as TinyPNG

Important! In R Markdown (i.e. in *.Rmd files but NOT *.md files), these Hugo shortcodes need to be escaped:

<!--html_preserve-->
{{< figure src = "name-of-image.png" width = "400" alt = "informative description">}}
<!--/html_preserve-->

2.4.3 Rmd-created images

When using our R Markdown template the knitr hook in the setup chunk actually creates the necessary Hugo shortcodes. Therefore you don’t need to worry about paths.

In the chunk producing a figure, use the hugoopts chunk option to control the alternative text and other elements. hugoopts is a named list that can have all elements described in the documentation of the Hugo figure shortcode except for title.

```{r chunkname, hugoopts=list(alt="alternative text please make it informative", caption="this is what this image shows, write it here or in the paragraph after the image as you prefer", width=300)} 
plot(1:10)
```

This chunk above produces a figure with “alternative text please make it informative” as alternative text, “title of the image” as title, “this is what this image shows, write it here or in the paragraph after the image as you prefer” as caption, and a width of 300 pixels.

2.4.4 Citations

To add citations, refer to them in the body of your post:

Citation of the primary literature[^1].
Citation of an R package[^2].
Citation of a website[^3].

And list your sources at the bottom of your post:

[^1]: Sciaini, M., Fritsch, M., Scherer, C., & Simpkins, C. E. (2018). NLMR and landscapetools: An integrated environment for simulating and modifying neutral landscape models in R. Methods in Ecology and Evolution, 9(11), 2240-2248. <https://doi.org/10.1111/2041-210X.13076>

[^3]: Hugo static site generator. https://gohugo.io/

2.4.4.1 Finding citations

To get the citation for an R package, run citation("packagename").

To get the citation for an article, you can use the RStudio Addin for rcrossref, or get the citation from a paper’s DOI by running e.g.

rcrossref::cr_cn("10.1111/2041-210X.13076", format="text", style="apa")

[1] "Sciaini, M., Fritsch, M., Scherer, C., & Simpkins, C. E. (2018). NLMRandlandscapetools: An integrated environment for simulating and modifying neutral landscape models inR. Methods in Ecology and Evolution, 9(11), 2240–2248. doi:10.1111/2041-210x.13076"

To get the citation for an article in Google Scholar, find the article, click the quote symbol (in search results under the article) to open the “Cite” window, and copy the APA style text.

2.4.5 Embedded tweets

Use a Hugo shortcode to embed a tweet using its ID e.g. {{< tweet 1138216112808529920 >}}. In R Markdown, shortcodes need to be html escaped, refer to the template for an example.

2.4.6 Examples

Comparing the raw Markdown to the live posts in these examples might be helpful.

• A blog post about a package that has passed software peer review. Compare raw markdown with the live post.

• A tech note. Compare raw markdown with the live tech note.

2.6.1 Knit post

If using the R Markdown template, knitting index.Rmd (RStudio knit button, or rmarkdown::render(<path_to_file>)) will generate both index.md and index.html ( index.html will be ignored, but we need an index.md). Commit both index.Rmd and index.md.

2.6.2 Check with roblog

You can use functions in the roblog package to do some automated checks on your post.

• ro_lint_md() to check and enforce use of complete alternative descriptions for image, of relative links to rOpenSci website, of Hugo shortcodes for tweets, of lower camelCase for rOpenSci name
• ro_check_urls() to check for URLs that might be broken

2.6.4 Local preview

If you wish to preview your post locally, as it will appear in our site, you must install Hugo. To install, refer to Hugo docs or run blogdown::install_hugo().

Note: You can also preview your blog post online through the pull request before the final submission

Then run hugo serve in the repo directory to start a local server on http://localhost:1313.

The version of Hugo used by the rOpenSci web server is defined in netlify.toml.

When this preview looks good to you, you should submit your post as a pull request.

2.7.1 Create draft pull request

• Open a draft pull request (PR) from your fork (using the web interface, see step 8 for creating a draft), or usethis::pr_push() that will save you some work and that will in the end open the same web interface where you can choose Draft PR in the last step)

• If you opened a PR instead of a draft PR, you can convert it to a draft by clicking on “Still in progress? Convert to draft” on the right panel under “Reviewers”.

2.7.2 Add checklist

In the first comment of your pull request submitting a post, please copy-paste the checklist corresponding to your post and check off the items.

2.7.3 Preview online

From the PR, Netlify will start building the new version of the site within seconds and you can preview your changes to make sure everything looks as intended. Otherwise push additional fixes till things look right.

2.7.4 Submit post

• Mark the draft PR as ready for review at least one week prior to the planned publication date. A review from blog editor(s) will be automatically requested by GitHub.
