I meant that the machine has Excel on it. Excel does not have to be running
prior to running the R code as the R code will start up and shut
down Excel itself.

Haven't got any feedback on this one.
Will we be getting a perl/python/ruby style -x switch for Rscript for R 2.5.0?
It certainly would give more flexibility to users of Rscript on non-UNIX systems
where #! notation is not available.

Good idea. ruby seems to work the same way. python does too but with
a slightly different definition:
C:\ ruby -h | findstr strip
-x[directory] strip off text before #!ruby line and perhaps cd to directory
C:\ perl -h | findstr strip
-x[directory] strip off text before #!perl line and
The help page for mean does not say what happens when one
applies mean to a matrix.
mean and sd work in an inconsistent way on a matrix
so that should at least be documented.
Also there should be a See Also to colMeans since that
provides the missing column-wise analog to sd.
On Windows XP with
R version 2.5.0 Under development (unstable) (2007-01-22 r40548)
I always get a message about grdevices when I run Rscript, e.g.
C:\ rscript NUL
During startup - Warning messages:
1: there is no package called 'grdevices' in: library(package, lib.loc = lib.loc

On UNIX one can use #! notation. It would be nice to be able to do something
similar on Windows.
This could be done by giving Rscript the capability of skipping over
the first few
lines. For example, there might be a --skip=n argument or perhaps Rscript would
skip over any consecutive leading
Good point. Perhaps what is needed is a Note clarifying all this in ?mean
(unless the software itself is reworked as Martin has discussed).
Regarding var(x), one could use sd(x)^2.

That's because your line is a point. Both components of the y vector
are equal. Check your parens.

You don't necessarily need to know C or C++ to write an R package.
Many (maybe most) R packages only use R.

I don't think it would be necessary to do any programming. Just run

thanks. Not knowing what is a quiet or noisy loop beforehand, I wouldn't like

These files make up a package,

I noticed the new environmentName in R 2.5.0dev. Thus I gather that
each environment has:
(1) a name
(2) a hex value
so
1. environmentName gets the name. Is there any way to set the name?
2. is there any way to get the hex value for an environment other than doing:
