Dear David and Aaron,

Aaron didn't have to install Tcl/Tk since this is now included in the R
installation. As well, although R will run under RStudio, I suggest that you
use it instead from R.app or from R running in a terminal window. Please see
the Rcmdr Mac OS X installation notes at
<http://socserv.socsci.mcmaster.ca/jfox/Misc/Rcmdr/installation-notes.html>
for more details.

Apparently the SparseM package wasn't installed when Aaron installed the
Rcmdr package. I'm not sure why that happened, but I've just installed the
Rcmdr package into a clean installation of R 3.2.0 under Mac OS X Yosemite
and experienced no problems -- perhaps the SparseM package was missing from
the CRAN mirror that Aaron used. Try installing the package directly via
install.packages("SparseM") and see whether that clears up the problem. If
the package is unavailable, try a different CRAN mirror.

Most Mac OS X Rcmdr problem relate to failing to install XQuartz but that
doesn't seem to be the case here. There are some other troubleshooting tips
in the installation notes mentioned above.

I hope this helps,
 John
