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 -- Erin Hodgess Associate Professor Department of Computer and Mathematical Sciences University of Houston - Downtown mailto: erinm.hodgess at

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 programming, as you presumably know; your query is not.

plotting confidence intervals
Hi R People: If I have a fitted values from a model, how do I plot the (1-alpha)100% confidence intervals along with the fitted values, please? Also, if the intervals are "shaded" gray, that would be nice too, please? I check confint, but that doesn't seem to do what I want.

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.

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 -- Erin

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 -- Erin Hodgess Associate Professor Department of Computer and Mathematical Sciences

solving equations symbolically
Dear R People: I have the following equation: $1 - \frac{R}{100} = \frac{2y}{10000}$ and I was wondering if there was a way in R to solve for R (no pun intended). I'm experimenting with Ryacas, but nothing yet. Version R-3.0.1 on Windows 7.
