Dear Pascale,
It seems an obvious question, so perhaps not worth asking, but did you
check that line 1 of the data file actually has 9 elements (separated by
white space)? (I notice that your as.is argument specifies 10 elements; I
don't believe that this should cause a problem if there are really 9.) If
inspection of the file doesn't reveal the problem, you could try to run
count.fields() on the file to see how many elements R thinks are in each line.
