Is this what you want? It returns a character vector with the values: > generate.index<-function(n.item){ + .return <- character() # initialize vector + for (i in 1:n.item) + { + for (j in ((i+1):n.item)) + { + # concatenate the results + .return <- c(.return, paste("i",formatC(i,digits=2,flag="0"),".",formatC(j,digits=2,flag="0"),sep="")) + + } + + } + .return + } > > > generate.index(10) [1] "i001.002" "i001.003" "i001.004" "i001.005" "i001.006" "i001.007" [7] "i001.008" "i001.009" "i001.010" "i002.003" "i002.004" "i002.005" [13] "i002.006" "i002.007" "i002.008" "i002.009" "i002.010" "i003.004" [19] "i003.005" "i003.006" "i003.007" "i003.008" "i003.009" "i003.010" [25] "i004.005" "i004.006" "i004.007" "i004.008" "i004.009" "i004.010" [31] "i005.006" "i005.007" "i005.008" "i005.009" "i005.010" "i006.007" [37] "i006.008" "i006.009" "i006.010" "i007.008" "i007.009" "i007.010" [43] "i008.009" "i008.010" "i009.010" "i010.011" "i010.010" >
