The aim of
devtools is to make your life as a package developer easier by providing R functions that simplify many common tasks. R packages are actually really simple, and with the right tools it should be easier to use the package structure than not. Package development in R can feel intimidating, but devtools does every thing it can to make it as welcoming as possible.
devtools comes with a small guarantee: if because of a bug in devtools a member of R-core gets angry with you, I will send you a handwritten apology note. Just forward me the email and your address, and I'll get a card in the mail.
How to install rtools in rstudio. Step – 1 Next comes installing RStudio; To install RStudio, go to download RStudio, click on the download button for RStudio desktop, click the link for the latest R version for your OS and save the.deb file; Step – 2 Download and install the gdebi package using the following commands.
devtools is opinionated about how to do package development, and requires that you use
roxygen2 for documentation and
testthat for testing. Not everyone agrees with these opinions, and they are by no means perfect, but they have evolved during the process of writing over 30 R packages. I'm always happy to hear about what doesn't work for you, and any places where devtools gets in your way. Either send an email to the rdevtools mailing list or file an issue.
Download and install R for Mac here. If you have trouble installing R on a Mac or Linux machine. Mac users do not need Rtools for package development.

Usage Arguments chooseversion Tool Option In R For Mac Os. If TRUE, allows the user to choose which version of RTools to install.
Updating to the latest version of devtools
You can track (and contribute to) development of
devtools at https://github.com/hadley/devtools. To install it:
Install the release version of
devtoolsfrom CRAN with
- 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 differnet flavors of Linux).
Follow the instructions below depending on platform.
Mac and Linux:
Package development tools
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 recommend practice.
Frequent development tasks:
load_all()simulates installing and reloading your package, loading R code in
R/, compiled shared objects in
src/and data files in
data/. During development you usually want to access all functions so
load_all()ignores the package
load_all()will automatically create a
document()updates documentation, file collation and
test()reloads your code, then runs all
Building and installing:
install()reinstalls the package, detaches the currently loaded version then reloads the new version with
library(). Reloading a package is not guaranteed to work: see the documentation to
build()builds a package file from package sources. You can can use it to build a binary version of your package.
install_github()installs an R package from github,
install_url()from an arbitrary url and
install_file()from a local file on disk.
install_version()installs a specified version from cran.
Check and release:
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_doc()runs most of the documentation checking components of
R CMD check
release()makes sure everything is ok with your package (including asking you a number of questions), then builds and uploads to CRAN. It also drafts an email to let the CRAN maintainers know that you've uploaded a new package.
bash()opens a bash shell in your package directory so you can use git or other command line tools.
wd()changes the working directory to a path relative to the package root.
dev_mode() will switch your version of R into 'development mode'. In this mode, R will install packages to
~/R-dev. This is useful to avoid clobbering the existing versions of CRAN packages that you need for other tasks. Calling
dev_mode() again will turn development mode off, and return you to your default library setup.

I recommend adding the following code to your

This will set up R to:
- always install packages from the RStudio CRAN mirror
- ignore newlines when
- give minimal output from

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:
