Hello Lars, from the read.table documentation:
row.names: a vector of row names. This can be a vector giving the actual row names, or a single number giving the column of the table which contains the row names, or character string giving the name of the table column containing the row names. Column numbering in R starts at 1 but you tell read.table to use the 0th column - this is consitent with your error message. The folowing works for me: > x <- read.table("bla", header=T) > x Subject Sex Age Gruppe Type Target.CRESP Target.RESP Target.RT 1 101 female 22 7 t 0 0 1520 2 101 female 22 9 o 0 1 3020 Prime.OnsetTime Target.OnsetTime Ordning Ident 1 155074 158497 101 145 2 161678 166005 102 160 -Marc -- ======================================================== Dipl.
