I may be making a simple error, but I've looked at the str() of the
resulting objects and I can't see any obvious reason I'm having the
problem I am having, so I am reaching out to the R-help group. I am
generating a string in my code. When I make a slight modification
(add a comma at the end using my "lastcomma" function), I can no
longer successfully write that string to a file. Specifically, the
resulting file contains only the "ⰱ" character. This occurs in:

Sample code:
h.long <- 150
task <- c(rep(1,h.long),rep(2,h.long))
ord <- sample(1:length(task))
task <- task[ord]
taskout <- paste(task,collapse=",")
write(file="please.txt",taskout)
lastcomma <- function(x) {return(paste(x,",",collapse="",sep=""))}
res <- lastcomma(taskout)
write(file="fail.txt",res)
cat(file="catfail.txt",res)
Any ideas as to how to avoid this problem would be appriciated as well
as suggestions as to whether this is expected behavior, or whether it
ought to be reported as a bug.
I don't see the problem in R version 2.10.1 Patched (2010-01-05 r50896)
nor in R 2.11.0 Pre-release (Windows Vista).
