Dear All,
Probably a one liner, but I am banging
I don't know if I understood your problem, but maybe you can retrieve
your columns simply in this way:
> DF$y
[1] 10 9 8 7 6 5 4 3 2 1
or (for looking at column)
> DF[2]
y
1 10
2 9
3 8
4 7
5 6
6 5
7 4
8 3
9 2
10 1
Bye

mn<-names(DF)
but then I cannot retrieve a column by doing e.g,
DF$mn[2]
I tried to play with the quotes and so on, but so f
