Hi,
The solution that works now is
closeAllConnections()
But even if I replace the 'list' with the 'array' I get a similar error.
"Exception is Error in UseMethod(\"close\"): no applicable method for
'close' applied to an object of class \"c('double', 'numeric')\"\n"
#Write each CPU's utilization data into a
#separate file
filelist.array <- function(n){
cpufile <- list()
cpufiledescriptors <- array(n,dim=c(0,n))
length(cpufile) <- n
for (i in 1:n) {
cpufile[[i]] <- paste("output", i, ".txt", sep = "")
cpufiledescriptors[i]<-file( cpufile[[i]], "a" )
}
listoffiles <- list(cpufile=cpufile,
cpufiledescriptors=cpufiledescriptors)
return (listoffiles)
}
Thanks,
Mohan

Hi Mohan,
I just ran the code within your function "filelist.array" and then was
able to close the connections I had created. I entered your function in R:
filelist.array<- function(n){
cpufile<- list()
cpufiledescriptors<- list()
length(cpufile)<- n
for (i in 1:n) {
cpufile[[i]]<- paste("output", i, ".txt", sep = "")
cpufiledescriptors[[i]]<-file( cpufile[[i]],
"a" )
}
listoffiles<- list(cpufile=cpufile,
cpufiledescriptors=cpufiledescriptors)
return (listoffiles)
}
and then:
filedescriptors<-filelist.array(3)
close(filedescriptors$cpufiledescriptors[[1]])
close(filedescriptors$cpufiledescriptors[[2]])
close(filedescriptors$cpufiledescriptors[[3]])
and it worked fine. Perhaps a typo in your code somewhere?
