Jan,
I'm not sure what you asking for. First, you cannot make read.table()
to output verbose message at every line read. Second, if you have
trouble to read you file, which looks like what you are showing, then
read ?read.table carefully. Most likely you wish to add argument
header=TRUE and sep="\t" (if it is a tab-delimited file).
