Hi,
I extracted from a data.frame (x) of 27 columns a smaller data.frame (x2) with
12 columns whit the following:
x2=x[, c("BROVISINGVal", "CHATVal", "EMAILVal", ..., "Piano.Tariffario")]
Anyway I want to form x2 by extracting all the rows that assume any value for
the first 11 columns but a particular value (2) for the last one
"Piano.Tariffario".
How do I continue?
Thanks
Sabrina
