doubt about options(graphics.record=T)
Hi all,
I've been using R under WindowsXP.
So, where the R stores the graphic archives (don't saved) if I use the option 
options(graphics.record=T) inside of Rprofile.site file?
Regards,

Didactic example and doubt: how to compare two regression line slopes
Hi,
I read almost all I found in prior R-Help list about How to compare
two regression line slopes.
So, I made a didactic example to illustrate a solution cited by Ben Bolker:

Doubt about Student t distribution simulation
Dear R list,
I would like to illustrate the origin of the Student t distribution using R.
So, if (sample.mean - pop.mean) / standard.error(sample.mean) has t 
distribution with (sample.size - 1) degree free, what is wrong with the 
simulation below? I think that the theoretical curve should agree with 
the relative frequencies of the t values calculated:

Arguments to utils:::menuInstallPkgs
Dears,
Is it possible (in any viable way) to pass arguments to the base function
(install.packages I think) using the utils:::menu?
For example:
> utils:::menuInstallPkgs(loc=.libPaths()[2])
> utils:::menuInstallLocal(loc=.libPaths()[2])
Thanks,

A couple of suggestions: source function (package base)
Hi,
I've been calling the function "source" (package base) from Tinn-R editor to
send files, marked blocks and selections to R interpreter because it avoids a
lot of problems related with input/output synchronization in the Rgui output!
The new RGedit plugin is also using this function in this way, and we are
finishing a new version of a plugin to Vim (Vim-R-plugin2) which uses

No, but why not just call install.packages directly?  (If you are using 
Rgui in Windows, you can add menu items using winMenuAddItem).

biplot package

So, I'm thinking to start a colaborative package to enhance this methods to other multivariate methods. In this
way, I would like to start it, making public a new function (biplot.pca, still in development, but running)

recommended way to group function calls in Sweave
Dear all
When using Sweave, I'm always hitting the same bump: I want to group
repetitive calls in a function, but I want both the results and the
function calls in the printed output. Let me explain myself.
Consider the following computation in an Sweave document:
summary(iris[,1:2])
cor(iris[,1:2])
When using these two calls directly, I obtain the following output:
> summary(iris[,1:2])
