Hi,
I am creating a list of 2 lists, one containing filenames
and the other file descriptors. When I retrieve them I am unable to close
the file descriptor.
I am getting this error when I try to call close(filedescriptors
[[2]][[1]]).
Error in UseMethod("close") :
no applicable method for 'close' applied to an object of class "c
('integer', 'numeric')"
print(filedescriptors[[2]][[1]]) seems to be printing individual elements.
Thanks,
Mohan
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)
}
#Test function
test.filelist.array <- function() {
filedescriptors <- filelist.array(3)
print(filedescriptors[[2]][[1]])
print(filedescriptors[[2]][[2]])
print(filedescriptors[[2]][[3]])
}
