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){
	if .Rdata (?????)
	load (.RData
	<run a command in linux like " cd ~/i/  ;  qsub job$i.pbs" >

Any idea how to do that in R?
