Try ?read.table or args(read.table). Might "skip=2" do what you want?
spencer graves p.s. I routinely "readLines(File, n=11)" to see how many headers there are AND identify the "sep" character. Then I "quantile(count.fields(File, ...))" to see if all records have the same number of fields. Then I call something like "read.table" with the appropriate arguments. Then I print the first 2 or so rows of the result to make sure I read the file correctly. mark salsburg wrote: > ok so the gct file looks like this: > > #1.2 (version number) > 7283 19 (matrix size) > Name Description Values > .... ....... ...... > > How can I tell R to disregard the first two lines and start reading > the 3rd line in this gct file.
