I'd _strongly_ recommend you don't use assign. Instead put everything in a list: paths <- dir("mydir", "\\.csv$", full.names = TRUE) names(paths) <- basename(paths) data <- lapply(paths, read.csv) molten <- lapply(data, melt, id = "Latitude", na.rm=TRUE) Hadley -- http://had.co.nz/ ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
