...ere in writing R code which will read in files with two variable parts to the file name and then assigning these file names to objects, which also have two variable parts. I have got the code running without encountering errors, however, I receive 50+ of the same warnings: 1: In assign(paste("Fekete_", index$year, index$month, sep = ""), ... : only the first element is used as variable name And it's true, when I do ls() only Fekete198601 has been assigned. I've attempted to rectify this, but have only come up against further errors. The code as it stands, is as follo...

...done this before on individual files, but this time I'm trying to do it on a directory of files (with variable file names) - therefore I have to also use the 'assign' command.
