Dear list,
I'm trying to download a text file directly from the internet using the RCurl package and the command getURL. Duncan Lang graciously helped me solve the first step in this problem using the following command:

txtfile <- getURL('ftp://ftp.wcc.nrcs.usda.gov/data/snow/snow_course/table/history/idaho/13e19.txt',
ftp.use.epsv = FALSE)

After searching many old posts, I can't find the solution to a simple problem.
can someone tell me how to create a character string with multiple backslashes, as in:

subset dataframe by rows using character vector?
Dear List,
I'm stuck on what seems like a simple indexing problem, I'd be very grateful to anyone willing to help me out.
I queried a dataframe which returns a character vector called "plot". I have another dataframe from which I want to subset or select only those rows that match "plot". I've tried subset, and also the "which" command.

regexpr syntax question
Greetings R list,
I am stuck on a simple syntax problem. I want to list all files in a directory, excluding files of a certain type. I have tried pattern matching as follows:
a <- list.files(data, full.name = TRUE, pattern != ".xml") # exclude all .xml files
The warning returns that my syntax is incorrect. I have read the regexpr help files and search old posts to no

64 bit Linux/Ubuntu memory limit problem?
Dear list,
I've recently installed R on a 64 bit machine with 8 GB of RAM. I set this computer up as a dual-boot system, with windows XP 64 and Ubuntu 7.10. I downloaded the Linux 64 bit version of R and installed it.
I'm trying to run rather large Random forest models and was running into severe memory limitations with my old windows 32 bit machines.

virtio for 9.1-R
Hi guys,
I can't see virtio in releng/9.1, is there any particular reason why it
isn't going to be included given that it works reasonable well (and is
optional anyway, so not likely to be detrimental)?
Thanks,
Joe

Samba not recognizing secondary groups
Hi all. I'm having a strange issue with a server running Samba 3.0.2a.
The server has a single share, and under that are subfolders that
contain documents. Each subfolder is owned by a different
folder-specific group, and users belong to the groups that own the
folders to which they need access.
But suddenly one user can't access any folders. Windows (the client)
suggests that she

linking icecast to ios and android phones
I think it's because the website uses Flash as first player instead of
using it as a fallback for when the browser does not support modern web
standards like the audio tag.

isolinux menu32 (Re: Problems booting on Intel i9x5 motherboards.)
See: http://syslinux.zytor.com/archives/2006-May/006887.html
I think I've tracked the problem down a bit more specifically.
In edd.S when the kernel calls int 0x13 with %dl=80 [primary disk] &
%al=1 [read one sector] and ah set to READ_SECTORS it never returns.
However, the following code [which does drive diagnostics] works.

ifelse statement
Hi, I am a newbie of R, and playing with the "ifelse" statement.
I have the following codes:
## first,
for(i in 1:3) {
for(j in 2:4) {
cor.temp <- cor(iris.allnum[,i], iris.allnum[,j])
if(i==1 & j==2) corr.iris <- cor.temp
else corr.iris <- c(corr.iris, cor.temp)
}
}
this code is working fine.
I also tried to perform the same thing in another way with "ifelse":

check2==1, 1,NULL))
so in my data frame I already have the check1 variable, if the conditions
(check1==1 & check2==1) is respected, check has to have 1 as value,

Hello everyone,
I have a (small) issue. I already googled a lot, so I decided to use ifelse

All the elements seem to work seperately, but combined in the ifelse
