Easily automate the following tasks to describe data frames: Summarise the distributions, and labelled missings of variables graphically and using descriptive statistics. For surveys, compute and summarise reliabilities (internal consistencies, retest, multilevel) for psychological scales. Combine this information with metadata (such as item labels and labelled values) that is derived from R attributes. To do so, the package relies on rmarkdown partials, so you can generate HTML, PDF, and Word documents. Codebooks are also available as tables (CSV, Excel, etc.) and in JSON-LD, so that search engines can find your data and index the metadata. The metadata are also available at your fingertips via RStudio Addins.

How to build a CLI for R, with npm.BackgroundThis blog post was triggered by a discussion on Twitter with MartinSkarzynski,who was looking for a way to build a CLI that launches an RScript.Here’s a way to do this using npm.Please note that this blog post won’t teach you how to build the commandline tool, it will quickly go over the way to create a system-widecommand line interface, using npm.If you want to learn more about building the utility, see thisfantastic series of blogpostsby Mark Sellor.Now, the idea is to have a CLI, i.e. a way to launch your utility with:$ mytoolAnd that, system-wide.What you’ll need An R script (script.R) with in it, for example:#!/usr/bin/env Rscript --vanillacli::cat_rule("yeay")cli::cat_bullet(Sys.time()) npm, which you can get fromthere.Let’s goCreate a new folder, and go inside it.mkdir cli && cd cliCreate the R Script there.echo '#!/usr/bin/env Rscript --vanilla' script.Recho 'cli::cat_rule("yeay")' script.Recho 'cli::cat_bullet(Sys.time())' script.RTry your script to see if it works:Rscript script.RNow launch an npm project:npm init -y(You can also run it without the -y to interactively add informationto the package.json.)Now the important part: add a "bin" value in the package.json, withthe name of the bin you want to create, and the path to the script,relatively to the package file. Here is an example of a package.json(I removed some elements).{ "name": "cli", "version": "1.0.0", "description": "CLI example with npm", "bin" : { "clir" : "./script.R" }, "author": "Colin Fay", "license": "MIT"}Install it globally (need sudo rights):sudo npm linkAnd, voilà! Open your terminal, and you’re done!clirOther way to go See the {littler}implementation

Yet another post with a focus on package documentation! This time, we’ll cover vignettes a.k.a “long-form package documentation”, both basics around vignette building and infrastructure, and some tips for more maintainer- and user- friendliness. What is a vignette? Where does it live? In this section we shall go over basics of package vignettes. Vignette 101 In the “R packages” book by Hadley Wickham and Jenny Bryan, the vignettes chapter starts with “A vignette is a long-form guide to your package.

This is a post I’ve been meaning to write for some time now about {capsule}. {capsule} provides alternative workflows to {renv} for establishing and working with controlled package libraries in R. It also uses an renv.lock so it is compatible with {renv} - you can switch between doing things the {capsule} way and the {renv} or vice versa at any time. Introducing an R package I wrote nearly three years ago Carefully curating a controlled package environment the {renv} way can be kind of a chore.
