It might be more efficient to do the following though:
i = 1:1000
fileNames =
paste("kegg.subrichcdt.",formatC(i,width=4,format="d",flat="0"),".txt",sep="")
So you now only have one vector containing all the names: then
for (i in 1:1000) {
temp = ## WHATEVER MAKES TEMP
write.table(temp,file = file.name[i])
}
should be faster. Depending on how temp is made, you could even coerce this
into the apply family (can't help you there unless you say more about
subrichcdt) for more speed if that's an issue for your proejct.
