[R] Read.table problem

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.
