Reading a csv file (db.csv) as:
yes,full
no,full
no,empty
I can use the command 'levels' to extract
the different values appearing for each
column as follows:
> d<-read.csv("db.csv")
> levels(d[,2])
which returns
> [1] "empty" "full"
while, doing the same with a numerical csv file as:
1,6
0,6
0,7
the same instruction returns an empty output instead of 6 7
Any idea about that?
Thanks in advance,
Alessandro
