How do I install an R package from source?

A friend sent me along this great tutorial on webscraping The New York Times with R. I would really love to try it. However, the first step is to install a package called [RJSONIO][2] from source.

I know R reasonably well, but I have no idea how to install a package from source.

I'm running macOS (OS X).

If you have source code you wrote yourself, downloaded (cloned) from GitHub, or otherwise copied or moved to your computer from some other source, a nice simple way to install the package/library is:

In R

It's as simple as:

# install.packages("devtools")
devtools::install('path/to/package')

From terminal

From here, you can clone a GitHub repo and install it with:

git clone https://github.com/user/repo.git
R -e "install.packages('devtools');devtools::install('path/to/package')"

Or if you already have devtools installed, you can skip that first bit and just clone the repo and run:

R -e "devtools::install('path/to/package')"

Note that if you're on ubuntu, install these system libraries before installing devtools (or devtools won't install properly).

apt-get update
apt-get install build-essential libcurl4-gnutls-dev libxml2-dev libssl-dev libfontconfig1-dev libharfbuzz-dev libfribidi-dev libfreetype6-dev libpng-dev libtiff5-dev libjpeg-dev -y

From CRAN, you can install directly from a GitHub repository address. So if you want the package at https://github.com/twitter/AnomalyDetection, using

library(devtools)
install_github("twitter/AnomalyDetection")

does the trick.

Download the source package, open Terminal.app, navigate to the directory where you currently have the file, and then execute:

R CMD INSTALL RJSONIO_0.2-3.tar.gz

Do note that this will only succeed when either: a) the package does not need compilation or b) the needed system tools for compilation are present. See: R for Mac OS X

In addition, you can build the binary package using the --binary option.

R CMD build --binary RJSONIO_0.2-3.tar.gz

If you have the file locally, then use install.packages() and set the repos=NULL: 

install.packages(path_to_file, repos = NULL, type="source")

Where path_to_file would represent the full path and file name:

  • On Windows it will look something like this: "C:\\RJSONIO_0.2-3.tar.gz".
  • On UNIX it will look like this: "/home/blah/RJSONIO_0.2-3.tar.gz".

A supplementarily handy (but trivial) tip for installing older version of packages from source.

First, if you call "install.packages", it always installs the latest package from repo. If you want to install the older version of packages, say for compatibility, you can call install.packages("url_to_source", repo=NULL, type="source"). For example:

install.packages("http://cran.r-project.org/src/contrib/Archive/RNetLogo/RNetLogo_0.9-6.tar.gz", repo=NULL, type="source")

Without manually downloading packages to the local disk and switching to the command line or installing from local disk, I found it is very convenient and simplify the call (one-step).

Plus: you can use this trick with devtools library's dev_mode, in order to manage different versions of packages:

You can install directly from the repository (note the type="source"):

install.packages("RJSONIO", repos = "http://www.omegahat.org/R", type="source")
