correct wording and notation for R stuff in LaTex
Hi R Gurus:
I'm putting together an article about some R stuff in Latex.
I refer to packages and functions.
I think that I use {\em} for packages and {\tt} for functions.
Is that correct, please?
Thank you in advance!
Sincerely,

I have a package that I am putting together.
I waited until the end to do the documentation and would like to

Is there a quick way to do this, please?

Newbie creating package with compiled code
Hi R Gurus!
I'm trying to create a test package using the package.skeleton function.
I wanted to add some compiled code too.
In the src library, I put together a baby subroutine, compiled it and created
a test.dll
When I use the R cmd build, it works fine. But I get into trouble
with the R CMD check section.
/home/Desktop/R-2.5.1/bin # ./R CMD check mypkg

builtin vs. closure
Dear R Gurus:
I'm working slowly through "R Programming for Bioinformatics", which
is really interesting!
Anyway, my question now is: what determines if a function is a
builtin vs. a closure, please?
For instance:
> typeof(sqrt)
[1] "builtin"
> typeof(mean)
[1] "closure"

strsplit
Hello R Gurus:
I would like to take a character string and split at the $ sign.
I thought that strsplit would do it, but here are the results:
> vv
[1] "whine$ts1"
> vv
[1] "whine$ts1"
> strsplit(vv,"$")
[[1]]
[1] "whine$ts1"
Does anyone have any suggestions, please?

[OT] Linux/UNIX question
Dear R Gurus:
I'm trying to find R on another Linux system.
I'm using the find command, (surprise), but I only want to see the
output where it exists, not all of the other stuff.
Is there an option that I could select, please?
Right now I have
find / -name R
TIA,

that please?
b. I don't know if the following is possible but here it is: I have
R and a bunch of libraries set up very nicely. I would like to hand

more environment questions
Hi R Gurus:
Here is some code that I was experimenting with, please:
> f1 <- function(x) {
+ e1 <- new.env(parent=.GlobalEnv)

+ return(mean(x))
+ }
> f1(1:15)
<environment: 0x02525444>

My question: why isn't the environment within the function set to e1, please?

density estimate
Hi R Gurus:
I have a tiny data set:
> xs
[1] 0.7 2.8 0.1 1.9 0.0 1.4 0.2 2.3 0.3 0.2

and generate the density function for it.
I would like to replicate this. Is there a straightforward way to do
this, please?
According to the help file, the FFT is used.
How does this compare to Silverman's version from his page 15 Equation
