Tools to Make Developing R Packages Easier

Jun 27, 2019 Hey everyone, I really need urgent help. My perfectly working RStudio suddenly stopped working entirely for not clear reason. I've tried uninstalling and reinstalling all the packages, but that just seemed to make the problem worse. Now I can't install almost any package without getting the non-zero exit status problem. When I try to install devtools, for example, I get the below.

Collection of package development tools.

Sep 17, 2016 How to Install R Packages using devtools on Ubuntu 16.04 Posted September 17, 2016 60.6k views Ubuntu Applications Ubuntu 16.04 R. We’ll load the shiny library, then run the first example. Because we are working on a remote server, we’ll specify the host address in order to browse from our local machine. Installation Mac Installation Install VirtualBox. VirtualBox Downloads. Install Homebrew. Homebrew Website. If Homebrew is already installed, then be sure to do a brew update. Tap the DevTools repository. Brew tap phase2/devtools. Install DevTools (and dependencies) brew install devtools. This will install the devtools binary as well the Docker and other dependencies. To install it: Install the release version of devtools from CRAN with install.packages ('devtools'). Make sure you have a working development environment. Windows: Install Rtools. Mac: Install Xcode from the Mac App Store. Linux: Install a compiler and various development libraries (details vary across different flavors of Linux). (if you are on Mac or Linux, then skip Rtools). Install.packages(' devtools ') library. Install.packages(c(' knitr ', ' kableExtra ', ' prettydoc ')) 3. Install the geospaar package. Note that the code below is a bit outdated, as the remotes package is the newer version for installs from remote repositories.

Readme

The aim of devtools is to make package development easier by providing R functions that simplify common tasks.

An R package is actually quite simple. A package is a template or set of conventions that structures your code. This not only makes sharing code easy, it reduces the time and effort required to complete you project: following a template removes the need to have to think about how to organize things and paves the way for the creation of standardised tools that can further accelerate your progress.

While package development in R can feel intimidating, devtools does every thing it can to make it less so. In fact, devtools comes with a small guarantee: if you get an angry e-mail from an R-core member because of a bug in devtools, forward me the email and your address and I'll mail you a card with a handwritten apology.

devtools is opinionated about package development. It requires that you use roxygen2 for documentation and testthat for testing. Not everyone would agree with this approach, and they are by no means perfect. But they have evolved out of the experience of writing over 30 R packages.

I'm always happy to hear about what doesn't work for you and where devtools gets in your way. Either send an email to the rdevtools mailing list or file an issue at the GitHub repository.

Updating to the latest version of devtools

You can track (and contribute to) the development of devtools at https://github.com/hadley/devtools. To install it:

Install.packages Devtools Library Devtools In Mac Download

Install the release version of devtools from CRAN with install.packages('devtools').
Make sure you have a working development environment.
- Windows: Install Rtools.
- Mac: Install Xcode from the Mac App Store.
- Linux: Install a compiler and various development libraries (details vary across different flavors of Linux).
Follow the instructions below depending on platform.
- Mac and Linux:
- Windows:

Package development tools

All devtools functions accept a path as an argument, e.g. load_all('path/to/path/mypkg'). If you don't specify a path, devtools will look in the current working directory - this is recommended practice.

Frequent development tasks:

load_all() simulates installing and reloading your package,loading R code in R/, compiled shared objects in src/ and datafiles in data/. During development you usually want to access all functions so load_all() ignores the package NAMESPACE.load_all() will automatically create a DESCRIPTION if needed.
document() updates documentation, file collation andNAMESPACE.
test() reloads your code, then runs all testthat tests.

Building and installing:

install() reinstalls the package, detaches the currently loaded version then reloads the new version with library(). Reloading a package is notguaranteed to work: see the documentation to unload() for caveats.
build() builds a package file from package sources. You canuse it to build a binary version of your package.
install_* functions install an R package:
- install_github() from github,
- install_bitbucket() from bitbucket,
- install_url() from an arbitrary url and
- install_local() from a local file on disk.
- install_version() installs a specified version from cran.

Check and release:

Install.packages Devtools Library Devtools In Mac

check() updates the documentation, then builds and checks the package. build_win() builds a package using win-builder, allowing you to easily check your package on windows.
run_examples() will run all examples to make sure they work.This is useful because example checking is the last step of R CMD check.
check_man() runs most of the documentation checking componentsof R CMD check
release() makes sure everything is ok with your package(including asking you a number of questions), then builds anduploads to CRAN. It also drafts an email to let the CRANmaintainers know that you've uploaded a new package.

Other tips

I recommend adding the following code to your .Rprofile:

See the complete list in ?devtools

This will set up R to:

always install packages from the RStudio CRAN mirror
ignore newlines when browse()ing
give minimal output from traceback()
automatically load devtools in interactive sessions

There are also a number of options you might want to set (in .Rprofile) to customise the default behaviour when creating packages and drafting emails:

devtools.name: your name, used to sign emails
devtools.desc.author: your R author string, in the form of 'Hadley Wickham <h.wickham@gmail.com> [aut, cre]'. Used when creating default DESCRIPTION files.
devtools.desc.license: a default license used when creating new packages
