You could try using tempfile() in combination with basename(). From the helppage on tempfile(): The names are very likely to be unique among calls to 'tempfile' in an R session and across simultaneous R sessions. The filenames are guaranteed not to be currently in use. So this is my suggestion for the generation of a useful, unique id in your working dir: prefix <- paste("var_", var, sep = "") while(file.exists(id <- basename(tempfile(pattern = prefix)))) {} save(result, file = paste(id, ".Rdata", sep = "")) Hope this helps.
