shared object for Rmpi
Dear R yet again!
I finally got the Rmpi package to install! Yay!.
However, when I go into R to use it, there is an error with the dyn.load
file.
This should be simple (allegedly).
Please help.
Thanks,
Sincerely,
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!
Sincerely,
Erin

Expressions and Functions
...nction is used for a symbolic derivative,
an expression is returned, which is fine.
How do you change that expression to a function, please?
I've been experimenting with substitute and deparse, but no success
yet.
This is R 1.8.0 for Windows.
thanks in advance for the help!

How would I do this, please?

Building R from source with the PGI compiler
...er.
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

read.pnm question in R-beta
...n I do the example from the read.pnm help file, this is what happens:
x <- read.pnm(system.file("pictures/logo.pgm",package="pixmap")[1])
Warning message:
In rep(cellres, length=2): x is NULL so the result will be NULL
In R-2.15.3, it's all right.
Thanks,
Erin

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,
Erin

combining strings

I want to end up with

What is the best way to achieve this, please? I was thinking that if
there is an exclusive "or" that it might work. I've tried all kinds
of ifs, and ifelse, to no avail.
Thanks,
