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,

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:

Doubts about chi-square distribution
Dear list,
For educational purposes I have been working with the script below.
I have a observation:
line 31
#CScal[i] = (amo^2) # IT IS WRONG, I KNOW, BUT IT MAKE R TO CRASHES!
I'm thinking this is a possible bug in the R!
And I have a couple of doubts:

#curve(dchisq(x, n-1), add = T, col = 'red'
I think that it is correct, but the function no

Help with a more flexible funtion for multiple comparision of means
Dear R-list,
Could anybody tell me (or give me a tip) of how to implement the Duncan
distribution in R?
I've been trying to make a new and more flexible function for multiple
comparison of means: Tukey, SNK and Duncan, from 'aov' objects, like TukeyHSD

Contingency tables from data.frames
Dear list,
I'm trying to do a set of generic functions do make contingency tables from
data.frames. It is just running "nice" (I'm learning R), but I think it can be
better.
I would like to filter the data.frame, i.e, eliminate all not numeric variables.
And I don't know how to make it: please, help me.

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,

Tables: Invitation to make a collective package
Hi All,
I would like to make an invitation to make a collective package with all
functions related to TABLES.
I know that there are many packages with these functions, the original idea is
collect all this functions and to make a single package, because is arduous for
the user know all this functions broadcast in many packages.
So, I think that the original packages can continue with its

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 II
Dear all,
I've been learning biplot (Gabriel, 1971) and some days ago I sent for
this list a procedural function with invitation for a collaborative package.
Jari Oksanen made some suggestions and I agree with all.
So, I reworked the function under the object-oriented programming
(OOP/S3). I think it is now a good frame for more resources.

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
