rmutil can be found here: http://popgen.unimaas.nl/~jlindsey/rcode.html : : Are there any others function to handle this. nf <- count.fields(myfile, sep = ",") z <- read.table(myfile, sep = ",", fill = TRUE, colClass = rep(numeric(), nf)) If the first line is longest you can omit the colClass argument and the nf computation. The above returns a data frame with one line per row and NAs at the end to fill it out as necessary. If you need a list of rows without the NAs: lapply(as.data.frame(t(data.matrix(z))), na.omit) ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
