Does file.exists answer to your question?
file.exists(".RData")
If you are not sure of the exact name of the file but know it contains
".RData", you can try:
List.files(directory,".RData")

Subject: [R] check availability of a file in R
I need to use a loop and each time go to folder i and check availability of
.RData file. If it exist load it and if not submit a command in linux.
Something like this
for (i in 1:10){
setwd(~/i/)
if .Rdata (?????)
load (.RData
else
<run a command in linux like " cd ~/i/ ; qsub job$i.pbs" >
}
Any idea how to do that in R?
Farhad
