Try read.table(choose.files(), row.names=NULL).
BTW, I think you might be using an older R version because in R-1.9.1,
the value for row.names is missing by default in read.table().
function (file, header = FALSE, sep = "", quote = "\"'", dec = ".",
row.names, col.names, as.is = FALSE, na.strings = "NA",
colClasses = NA, nrows = -1, skip = 0, check.names = TRUE,
fill = !blank.lines.skip, strip.white = FALSE,
blank.lines.skip = TRUE, comment.char = "#")
Try read.delim() or read.csv() if the data is tab-delimited or comma
separated. Also check to see if you have a header, in which case you
would set the option header=TRUE. For more info, help("read.table").
Do dim(m), head(m) to see if the data has been read correctly.
