How to install EZR on MacOS X
1) Download R installer from the The Comprehensive R Archive Network homepage (Download R for MacOS X). Install R and run R. Install it on the main
hard drive.
2) EZR requires X11 windows system, but it may not be installed in OS X
Mountain Lion or later versions. X11 windows system can be installed from
a WEB site, http://xquartz.macosforge.org.
If EZR does not work properly, repeat this procedure.
3) Open R.app and type
install.packages("RcmdrPlugin.EZR", dependencies=TRUE)
after ">" in the R console and push the Enter key.
4) To run R commander, type
library(Rcmdr)
after ">" in the R console and push the Enter key. Answer
"Yes" to the question (if shown) whether the user wants to install
packagees that are required by Rcmdr. If this procedure does not work properly,
Type
install.packages("Rcmdr", dependencies=TRUE)
after ">" in the R console and push the Enter key to install
packages required by R commander, and then, repeat 3). EZR can be loaded
by selecting RcmdrPlugin.EZR from the "Tools" > "Load
Rcmdr plug-in(s)" menu in the R commander window. Answer "Yes"
to "Restart now?".
5) EZR will start at the same time with launching R, if following 6 lined

options(Rcmdr=list(plugins='RcmdrPlugin.EZR'))
local({
old <- getOption('defaultPackages')
options(defaultPackages = c(old, 'Rcmdr'))
})
These can be done by opening the Terminal.app located in the Utilities
