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

🔗 R-universe

Video and resources from our past community call about rOpenSci’s R-universe Project were posted. The R-universe platform is a new umbrella project under which rOpenSci experiments with new ideas for improving publication and discovery of research software packages in R. In this 1-hour community call, Jeroen Ooms explained the basic steps of setting up your own universe, and getting started with publishing packages (including experimental software, development versions, research compendia) and articles on your personal subdomain.

For getting help with R-universe please use the R-universe bugs repository.

🔗 rOpenSci at useR! 2021

Registration for the useR! 2021 conference closes June 25th! Early Bird rates now apply until Registration closes. useR! conferences are non-profit conferences organized by community volunteers for the community, supported by the R Foundation. useR! 2021 will take place online.

Important note, you can view the conference schedule in the timezone of your choice.

Get excited for four contributions by rOpenSci staff members:

• Jeroen Ooms, rOpenSci Lead Infrastructure Engineer, will give a keynote talk about the R-universe project on Friday, July the 9th at 12:30PM – 1:30PM UTC.

• Stefanie Butland, rOpenSci community manager, will present on rOpenSci’s Model for Managing a Federated Open Source Software Community on Monday, July the 5th at 5:05PM UTC in a session starting at 4:45PM UTC.

• Mark Padgham, rOpenSci Software Research Scientist, will also give a regular talk about his original autotest package for automatic testing of packages, on Tuesday, July the 6th at 8:45AM UTC (right at the beginning of the session).

• Maëlle Salmon, Research Software Engineer with rOpenSci, will give a tutorial, GET better at testing your R package! on Wednesday, July the 7th at 7-10AM UTC. This tutorial is about advanced testing of R packages, with HTTP testing as a case study. The tutorial has no spots left, but it will be recorded and materials are available online.

Also very exciting is community member Lluís Revilla Sancho’s talk about Packages submission and reviews; how does it work? using data about review process of three archives of R packages, CRAN, Bioconductor and rOpenSci. That talk will happen in the same session as Stefanie Butland’s presentation.

🔗 Software ?

🔗 New packages

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

• autotest, developed by Mark Padgham: Automatic testing of R packages via a simple YAML schema.

• pkgcheck, developed by Mark Padgham: Check whether a package is ready for submission to rOpenSci’s peer review system.

• pkgstats, developed by Mark Padgham: Metrics of R packages.

• roreviewapi, developed by Mark Padgham: Plumber API to report package structure and function.

• srr, developed by Mark Padgham: Companion package to rOpenSci statistical software review project.

• dataspice, developed by Bryce Mecum together with Carl Boettiger, Scott Chamberlain, Auriel Fournier, Kelly Hondula, Anna Krystalli, Maëlle Salmon, Kate Webbink, Kara Woo: The goal of dataspice is to make it easier for researchers to create basic, lightweight, and concise metadata files for their datasets. These basic files can then be used to make useful information available during analysis, create a helpful dataset “README” webpage, and produce more complex metadata formats to aid dataset discovery. Metadata fields are based on the Schema.org and Ecological Metadata Language standards. It is available on CRAN. It has been reviewed by T D James, Abby Bratt.

🔗 Use cases

Two use cases of our packages and resources have been reported since we sent the last newsletter.

• Using tabulizer to extract tabular data from daily COVID-19 reports. Reported by Steffi LaZerte.

• Using rotl to create phylogenetic trees. Reported by Denise.

Explore other use cases and report your own!

🔗 Call for maintainers

There’s no open call for new maintainers at this point but you can refer to our contributing guide for finding ways to get involved! As the maintainer of an rOpenSci package, feel free to contact us on Slack or email [email protected] to get your call for maintainer featured in the next newsletter.

🔗 Package development corner

Some useful tips for R package developers. ?

🔗 Dependency analysis

Have you ever wondered why package Y needed package X, i.e. what the dependency relation between them is? Whilst there are base R tools for finding this out, the pak package by Gábor Csárdi provides a nice function for doing just that, pkg_deps_explain(). E.g.

• if you wonder, why is curl needed to use pkgdown?

• you type pak::pkg_deps_explain("pkgdown", "curl").

• you get: pkgdown -> httr -> curl.

You can even use the local package or a GitHub package as first argument. Also worth mentioning is pkg_deps_tree() for drawing the dependency tree of a package. Note that this is all in pak development version.

🔗 Reducing the complexity of code

When trying to reduce the complexity of your code (for making it easier to maintain and review), check out the cyclocomp package, also by Gábor Csárdi, as reminded by Lluís Revilla Sancho in rOpenSci semi-open slack: it will help you find functions that are too complex.

Another package that might help you clean your code is the rOpenSci peer-reviewed Rclean package by M.K. Lau.
