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

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.
Thanks in advance,
Sincerely,
Erin

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,
Erin

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

Dear R Gurus:
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!

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

2009-04-26 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,

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,
Erin

as.integer question

I'm reading "Statistical Computing with R", by Maria Rizzo, and it's
really good.
Anyhow, I have a question about something in there.

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

Hi,
If you are using roxygen-style function documentation then why not use devtools::document()?

Is there a function to convert a character string to all uppercase or
all lowercase please?
I'm sure that I've used one before but I'm drawing a blank.

setting breaks in hist
Dear R People:
Is there a way to "guarantee" that breaks=n will give you exactly n
breaks, please?
I'm fairly certain that the answer is "no", but thought I'd check.

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.
Thanks,
Erin
