Notes on installing R and modules
R is a potent, open-source tool and environment for doing reporting, data and statistical work including visualisations. I have notes on using R
Getting up and running
You can download the installer from the website or use Homebrew to install it.
- normal install https://www.r-bloggers.com/installing-r-on-os-x/
- homebrew https://www.r-bloggers.com/installing-r-on-os-x-100-homebrew-edition/

The basic package is a command-line application, but the installer comes with a GUI. For an even more powerful environment one can install R-Studio.
I am interested in using computers to analyse text and so I thought that RQDA looked like a useful tool to do that with.
But installing it is terribly painful.
There are the R packages that can be installed directly, or you can use the github version
The issue seems to be RGtk2 not building against X11/XQuartz correctly.
1st approach: install older GTK w/X11
- download and install a GTK build with X11 from http://r.research.att.com/
we now need to point various things to this framework, so in your .bashrc add
trying to build things against this fails to locate a gdk file, we we need to edit one of the pkg-config files:
sudo vi /Library/Frameworks/GTK+.framework/Resources/lib/pkgconfig/gdk-x11-2.0.pc add -I/opt/X11/include
build successful, we can then start building our R packages now.
R CMD INSTALL RGtk2_2.20.31.tar.gz
and it builds successfully, but doesn’t load correctly, and so fails to install.
2nd approach: wrangling Homebrew
The gist of the issue seemed to be that Homebrew’s gtk was bulid with XQuartz in mind rather than X11 and that RGtk2 was built against Gtk with X11 and not Gtk with XQuartz.
It was this seemingly irrelevant post that put me on the path to solving this.
first, Homebrew’s cairo needs to be reinstalled with X11 support:
brew uninstall –ignore-dependencies cairo brew install cairo –with-x11
then we need to change the configuration of Homebrew to build Gtk2 as we want:
brew edit gtk under ‘def install’, change –with-gdktarget to =x11 append “–with-x” to the list
now build Gtk:
brew install –build-from-source –verbose gtk
now for the R packages
R CMD INSTALL RGtk2_2.20.31.tar.gz R CMD INSTALL cairoDevice_2.24.tar.gz
another failure, this time for igraph; but from https://github.com/hadley/xml2/issues/127 we can
cp /usr/bin/xml2-config to ~/bin/ (or maybe /use/local/bin) edit this xml2-config to make line 3 prefix=/usr
R CMD INSTALL igraph_1.0.1.tar.gz
Complete! And as a bonus, this process also enables rattle to install
- a similar issue with building against X11 https://trac.macports.org/ticket/13429
- rattle is a similar tool which has a similar build failure, and this post goes through installing that http://marcoghislanzoni.com/blog/2014/08/29/solved-installing-rattle-r-3-1-mac-os-x-10-9/
