Hello!
Thanks!
I changed the "," to "." in both datafile and code but the problem remains
identical.
Then we will need a reproducible example, as requested in the message
footer.
BTW, your example is a perfect illustration of the problem. Unless spaces
are significant (and they are not in general in R nor in most computer
languages)
1,00, 0,54, 0,00
looks just like
1, 00, 0, 54, 0, 00
and R's parser takes it as such.
Cheers!
Jojje
