See ?read.table. read.table() will work if there are seperators beween missing values (you have to specify 'sep' in that case!). If the number of separators is unequal for some lines, the argument 'fill' might help. If not, consider to use scan() or readLines() and postprocess the imported stuff. Uwe Ligges
