write.csv
Hi,
I want to save an array(say, array[6,7,8]) write a cvs file. How can I do
that??? can I write in one file?
if I could not write in one file, i want to use a loop to save in different
files (in the array[6,7,8], should be 8 csv files), such as the filename
structure should be: file ="filename" +str(i) +"." +"csv"
Many thanks.

assign value between different type: Double vs Integer
Dear list,
just to put it in a simple way:
i read.csv from csv file to create a gdata
then, create array gdata34
however, when making a loop for assigning gdata34[1,m]<-gdata[m,4], this is what happen
gdata[1,4] 's real value is 10354, however, the gdata34[1,4] turns to be 883
then i checked the type: gdata[1,4] is integer, while gdata34[1,4] is double.
Can any one give me some help

[OT] putting URLs in Latex
Hi R Gurus!
This is definitely off topic, but I thought I'd try: what is the way
to put in url's into a Latex file, please?
I know that you start with a \newcommand statement, with some kind of
argument that will change, but I'm not sure how to set it up, please.

generating .Rd files
Hi R Gurus!
I have a package that I am putting together.
I waited until the end to do the documentation and would like to
generate a set of "empty" .Rd files.
Is there a quick way to do this, please?
Thanks,

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?

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"

[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,

more environment questions
Hi R Gurus:
Here is some code that I was experimenting with, please:
> f1 <- function(x) {

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

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