I have no idea what I'm doing but I need to use R and Rcmdr for my statistics class. I am running OS X 10.7.5, using 3.1.2 for R.

I have downloaded R.

install.packages("Rcmdr")

Picked a mirror, downloaded all packages. I then typed in

library(Rcmdr)

And received this error:

Loading required package: splines
Loading required package: RcmdrMisc
Loading required package: car
Loading required package: sandwich
Error : .onLoad failed in loadNamespace() for 'tcltk', details:
  call: system2("otool", c("-L", shQuote(DLL)), stdout = TRUE)
  error: error in running command
Error: package or namespace load failed for ‘Rcmdr’
sh: otool: command not found

When I do:

capabilities("tcltk")
# [1] TRUE

Have I done something wrong?

The R developers have tried to make a workaround for R not giving a useful error message when Tcl/Tk was not fully supported on a Mac. It seems R 3.1.2 depends on the otool from Xtools for this. However, you can download a patched version of R from http://r.research.att.com/ to remove the error.
