R interprets that you have 42 columns from the variable names. Do you? See
if removing spaces between column names helps (e.g., "week.1" instead of
"week 1"). Also, because yours is a csv file, fields are separated by
comas. You can either use the "read.csv" command instead of the
"read.table" (see ?read.table for details), or add the argument sep="," to
tell R that fields are separated by comas. You might also need to specify,
if you have empty cells, what to do with them (e.g., na.strings="")
