Dear rOpenSci friends, it’s time for our monthly news roundup!

You can read this post on our blog. Now let’s dive into the activity at and around rOpenSci!

rOpenSci HQ

Community call recording: Navigating the R ecosystem using R-universe

Video and resources.

Learn more about R-Universe and how you can use it to improve your R package development workflow.

In this community call, Jeroen Ooms provided details on what R-Universe is and an update on what you can do with it today. He also discussed the future of R-Universe and how it can be used to navigate the R ecosystem.

R-Universe list pages

R-Universe now features a list of all datasets in all packages and a list of all vignettes from CRAN, Bioconductor, and others.

Another important global table is the package scoreboard that lets you explore the scores used by R-Universe search engine for ranking, which is based on:

• Stars: Number of stars on GitHub;
• Downloads per month from CRAN or Bioconductor mirrors;
• Scripts: (NEW) number of files on GitHub that mention ’library(pkgname)’;
• Dependents: recursive reverse dependencies;
• Unique contributors;
• Yearly commits.

Resources from rOpenSci training sessions

We’ve added a searchable table of past training sessions to our resources hosted on the rOpenSci website. Explore the full list of our resources.

Coworking

Read all about coworking!

Join us for social coworking & office hours monthly on first Tuesdays! Hosted by Steffi LaZerte and various community hosts. Everyone welcome. No RSVP needed. Consult our Events page to find your local time and how to join.

• Tuesday, October 1st, 14h00 Europe Central (12:00 UTC), “Using R to tell (data science) stories” with cohost Apoorv Anand and Steffi LaZerte.
  • Explore how others use R to tell data stories
  • Start work on a project using R to craft a narrative through data
  • Chat with our cohost to discuss and explore the use of R in data stories

And remember, you can always cowork independently on work related to R, work on packages that tend to be neglected, or work on what ever you need to get done!

Software 📦

New packages

The following two packages recently became a part of our software suite:

• eDNAjoint, developed by Abigail G. Keller: Models integrate environmental DNA (eDNA) detection data and traditional survey data to jointly estimate species catch rate (see package vignette: https://bookdown.org/abigailkeller/eDNAjoint_vignette/). Models can be used with count data via traditional survey methods (i.e., trapping, electrofishing, visual) and replicated eDNA detection/nondetection data via polymerase chain reaction (i.e., PCR or qPCR) from multiple survey locations. Estimated parameters include probability of a false positive eDNA detection, a site-level covariates that scale the sensitivity of eDNA surveys relative to traditional surveys, and catchability coefficients for traditional gear types. Models are implemented with a Bayesian framework (Markov chain Monte Carlo) using the Stan probabilistic programming language. It has been reviewed by Chitra M Saraswati and Saras Windecker.

• rix, developed by Bruno Rodrigues together with Philipp Baumann: Simplifies the creation of reproducible data science environments using the Nix package manager, as described in Dolstra (2006) . The included rix() function generates a complete description of the environment as a default.nix file, which can then be built using Nix. This results in project specific software environments with pinned versions of R, packages, linked system dependencies, and other tools. Additional helpers make it easy to run R code in Nix software environments for testing and production. It is available on CRAN. It has been reviewed by David Watkins and Jacob Wujiciak-Jens.

Package development corner

Some useful tips for R package developers. 👀

How to demonstrate an error in an R Markdown vignette

An useful piece of information shared by Hugo Gruson in our Slack workspace. To demonstrate an error in a vignette, try setting purl = FALSE in chunks with error = TRUE. More info in a knitr issue.

Better titles for roxygen2 “family” cross-references

Do you use the “family” roxygen2 tag for grouping and cross-linking manual pages? Did you know you can override the default title from, for instance, “Other blabla” to “blabla functions and related data”? If not, refer to roxygen2 documentation.

Create and use a custom roxygen2 tag

Read more about creating a custom tag that adds a new section to a manual page in this blog post by Maëlle Salmon.

Materials from posit::conf(2024) workshops

Materials from posit::conf(2024) workshops have been posted. Especially relevant to package developers: From R User to R Programmer by Emma Rand and Ian Lyttle; and Package Development: The Rest of the Owl by Jenny Bryan whose introduction slidedeck features GitHub search tips.

Some tips when searching GitHub issues

Speaking of GitHub search…

Michael Chirico shared the following tip on Mastodon: “[you can use] the ‘in:title’ operator in GitHub search to restrict a search to issues/PRs matching a query in the title”.

Jenny Bryan answered with another tip: “involves:USERNAME” for “I was once part of a conversation about this”.

A usethis function to create a test helper file

The new usethis function usethis::use_test_helper("mocks") will create a helper file under tests/testthat/helper-mocks.R.

A devtools function for building the README and vignettes

Not a new function, but in case you missed it… The devtools::build_rmd() and devtools::build_readme() functions render R Markdown files using a temporary install of your current development package.
