Over the past years, R has been gaining popularity, bringing to life new tools to with ith it. Thanks to the amazing work by contributors implementing the Language Server Protocol for R and writing Visual Studio Code Extensions for R, the most popular development environment amongst developers across the world now has very strong support for R as well.
In this post, we will look at the languageserversetup package that aims to make the setup of the R Language Server robust and easy to use by installing it into a separate, independent library and adjusting R startup in a way that initializes the language server when relevant.
It is almost the 29th of February 2020! A day that is very interesting for R, because it marks 20 years from the release of R v1.0.0, the first official public release of the R programming language.
In this post, we will look back on the 20 years of R with a bit of history and 3 interesting perspectives - how much faster did R get over the years, how many R packages were being released since 2000 and how did the number of package downloads grow.
It is Christmas time again! And just like last year, what better time than this to write about the great tools that are available to all interested in working with R. This post is meant as a praise to a few selected tools and packages that helped me to be more efficient and productive with R in 2019.
In this post, we will praise free tools that can help your work become more efficient, reproducible and productive, namely the data.
In the previous post, we focused on setting up declarative Jenkins pipelines with emphasis on parametrizing builds and using environment variables across pipeline stages.
In this post, we look at various tips that can be useful when automating R application testing and continuous integration, with regards to orchestrating parallelization, combining sources from multiple git repositories and ensuring proper access right to the Jenkins agent.
Running stages in parallel Parallel computation using R Orchestrating parallelization of R jobs with Jenkins Failing early Cloning multiple git repositories Cloning into a separate subdirectory Cleaning up Changing permissions to allow the Jenkins user to read References Running stages in parallel Parallel computation using R There are numerous way to achieve parallel computation in the context of an R application, those native to R are for example
Jenkins is a popular open-source tool that helps teams with automation and implementation of continuous integration and deployment pipelines, comparable to for example Atlassian’s Bamboo, GitLab CI or to some extent Travis.
In this post, we share some practical lessons learned when integrating R applications via Jenkins for the purpose of continuous integration and regression testing on runner nodes configured using Jenkins via declarative pipelines defined in a Jenkinsfile.
Recently I was involved in a task that included reading and writing quite large amounts of data, totaling more than 1 TB worth of csvs without the standard big data infrastructure. After trying multiple approaches, the one that made this possible was using data.table’s reading and writing facilities - fread() and fwrite().
This motivated me to look at benchmarking data.table’s fread() and how it compares to other packages such as tidyverse’s readr and base R for reading tabular data from text files such as csvs.
As pointed out by a recent read the R source post on the R hub’s website, reading the actual code, not just the documentation is a great way to learn more about programming and implementation details. But there is one more activity to get even more hands-on experience and understanding of the code in practice.
In this post, we provide tips on how to interactively debug R code step-by-step and investigate the values of objects in the middle of function execution.
As we wrote in Should you start your R blog now?, blogging has probably never been more accessible to the general population, R users included. Usually, the simplest solution is to host your blog via a service that provides it for free, such as Netlify, GitHub or GitLab Pages. But what if you want to host that awesome blog on your own, HTTPS enabled domain?
In this post, we will look at how to port a Hugo-based website, such as a blogdown blog to our own domain, specifically focusing on GitLab Pages.
It has been a year since I posted the first post on this blog. Since that time, I have learned many lessons, but the main one is probably that blogging has never been as accessible as it is now.
In this anniversary post, I would like to give you a few reasons to start your own R blog and write about what I have learned in my first year of blogging about R.
If the practical tips for R Markdown post we talked briefly about how we can easily create professional reports directly from R scripts, without the need for converting them manually to Rmd and creating code chunks. In this one, we will provide useful tips on advanced options for styling, using themes and producing light-weight HTML reports directly from R scripts. We will also provide a repository with example R script and rendering code to get different styled and sized outputs easily.
