[R] snowfall sfInit error
Dear all,
I am trying to execute the simple example in snowfall
http://cran.r-project.org/web/packages/snowfall/vignettes/snowfall.pdf ...
require(snow)
require(snowfall)
sfInit( parallel=TRUE, cpus=2 )
sfLapply( 1:10, exp )
sfStop()
I have installed the snow and snowfall packages in R on a machine with
windows xp, however, after running the "sfInit( parallel=TRUE, cpus=2 )"
line I get an error ...
Error in system("whoami", intern = TRUE, ignore.stderr = TRUE) :
whoami not found
Error in paste(sep = "_", "R", uname, format(Sys.time(),
"%H%M%S_%m%d%y")) :
object "uname" not found
I am the only (administrator) user of the computer. It has a dual core
processor, and is not networked.
I would be greatful if someone could tell me how to proceed.
Kind regards
Chibisi

Re: [R] Reading tables using a truncated name
Hi all,
Thanks everyone for your advice. They have been helpful.
Just for the record, I am using ...
lapply(dir(path = filePath, pattern = "^test_"), function(x){read.table(file
= paste(filePath, x, sep = ""), sep = ",", header = TRUE) } )
to load the files
kind regards
Chibisi

[R] Reading tables using a truncated name
Dear all, I am trying to read a bunch of csv files using read.table() that are named "test_xx.csv" where "xx" has no particular pattern. Is there a way of reading all the files by specifying a truncated file name e.g. "test_" with some wild card characters, or would I have to laboriously create some vector with the "xx" names and iterate or lapply() over it?
