Any ideas why read.table complains about not correct number of elements in 
line
while readLine/strsplit indicate that all lines have the same number of 
elements ?

R


> tbl <- read.table('tmp', header = T, sep = '\t')
Error in scan(file = file, what = what, sep = sep, quote = quote, dec = 
dec,  : 
        line 32 did not have 27 elements
> lines <- readLines('tmp')
> v <- 1:length(lines)
> i <- 0; for (line in lines) { i <- i + 1; v[i] <- length(strsplit(line, 
'\t')[[1]]) }
> v
