What is the name of the person who has all of the Tcl/tk stuff,

I wanted to look at some of his examples.
Thanks in advance!

Building R from source with the PGI compiler
Hello
I would like to build R from source and use the PGI compiler, rather than
the GCC compiler.
I saw the instructions for the Intel compiler in the R Installation Manual,
but I didn't see the PGI. I tried a few times without instructions, but
without success.
Any suggestions would be most welcome. Also, I hope this is the right
group for the question.
Sincerely,
Erin

tables
Dear R People:
I have generated the following table:
> table(zza$DEATH,zza$GENDER)
F M
2009-04-21 0 1
2009-04-22 4 2
2009-04-24 6 0
2009-04-25 1 3
2009-04-26 2 0
2009-04-28 3 0
2009-04-29 2 2
However, instead of total counts in the F and M columns, I would like percents.
How would I do this, please?
thanks,

Is there a way to find which objects are functions via ls(), please?
I'm sure that there is, but I'm not sure how.

R on an iPad
Dear R People:
Is it possible to run R on an iPad, please?
For some reason, I'm thinking that you can't have Fortran, C, etc., so
you can't do it.
But I thought I would check anyway.
Thanks,

attr question
Dear R People:
When I want to produce a small sample confidence interval using
t.test, I get the following:
> t.test(buzz$var1, conf.level=.98)$conf.int
[1] 2.239337 4.260663
attr(,"conf.level")
[1] 0.98
How do I keep the attr statement from printing, please? I'm sure it's
something really simple.
Thanks,
Sincerely,

r-package-devel is probably a better place to post this, especially if
you do not get a satisfactory reply here. This list is about R

tcltk problems
When I have compiled from sourced on Ubuntu, I did NOT include the

substring/strsplit question
Dear R People:
Here is a toy example:
> x <- c("2E","5W","12H")

[1] "E" "W" "2"

Sometimes x has 3 elements, sometimes 2. I want to extract the last
element, and then extract the other 1 or 2 elements.
How can I do this, please?
TIA,
Sincerely,

replicating C example from the Extensions Manual problem
Dear R People:
Here is something that I am sure is very simple. I'm just trying to
re-create the C convolution example in the Extensions manual. Here is
the subroutine:
void convolve(double *a, int *na, double *b, int *nb, double *ab)
{
R_len_t i, j, nab = *na + *nb - 1;
for(i = 0; i < nab; i++)
ab[i] = 0.0;
for(i = 0; i < *na; i++)
for(j = 0; j < *nb; j++)
ab[i + j] += a[i] *

determining if a function exists in a particular package
Hello R People:
Is there a way to determine if a function exists in a particular
package, please?
I looked at exists and objects, but they seem to refer to an
environment rather than a package.
I was thinking of something like:
ifelse(exists(functiona) in MASS, print(1:10), print(5))
Thanks,
Erin

omitting columns from a data frame
Dear R People:
I have a data frame, xm1, which has 12 rows and 4 columns.
If I put is xm1[,-4], I get all rows, and columns 1 - 3, which is as
it should be.
Now, is there a way to use the names of the columns to omit them, please?
Thanks so much in advance!

a really simple question on polynomial multiplication
Dear R people:
Is there a way to perform simple polynomial multiplication; that is,
something like
(x - 3) * (x + 3) = x^2 - 9, please?
I looked in poly and polyroot and expression. There used to be a
package that had this, maybe?
thanks,
