Dear Simon,
That's a good suggestion. In fact, I don't see a real function for
the
technical details, so I've just eliminated them. I also think that
adding
the step to run Software Update is harmless and a good idea, so
I've added
that. The full set of instructions (including the parts that I
omitted
earlier) now reads:
----------------- snip -------------
These instructions are for R version 3.0.1 or later; if you're
using an
earlier version of R, I suggest that you upgrade, or, failing
that, consult
the special Mac OS X installation notes for the R Commander under
older
versions of R. R 3.0.1 only supports Mac OS X version 10.6.8 (Snow
Leopard)
or greater.
O Before installing R and the R Commander, make sure that your Mac
OS X
system is up-to-date by running Software Update from the "apple"
menu at the
top-left of the screen. This is important, because R assumes that
the system
is up-to-date and may not function properly if it is not.
O Install R 3.0.1 or later from the Comprehensive R Archive
Network (CRAN),
selecting a mirror site near you; a list of CRAN mirrors appears
at the
upper left of the CRAN home page.
O Install XQuartz from http://xquartz.macosforge.org. (The R
Commander uses
the tcltk package for R, which requires X-Windows. Your Mac may
already have
X-Windows installed, but it should not hurt in any event to
install
XQuartz.)
O Start R by running R.app. At the R > command prompt, type the
following
command and press the return key (to avoid errors, you can copy
the command
from this document and paste it at the R > command prompt):
install.packages("Rcmdr")
R will ask you to select a CRAN mirror; pick a mirror site near
you.
O Once it is installed, to load the Rcmdr package, simply issue
the command
library(Rcmdr)
at the R > command prompt and press return. When you first load
the Rcmdr
package, it will offer to download and install missing
dependencies; allow
it to do so.
----------------- snip -------------
There's no need to respond again if you think these instructions
are OK.
Thanks again,
John
