Hi,
thanks for help on index in a for for looping. its work.
Now I have another doubt.
I have a data.frame like this:
nsps area
1 1 4
2 0 9
3 1 4
4 1 4
5 1 4
6 1 9
7 0 4
8 1 9
9 0 4
10 1 9
...
I try to make another data.frame like this:
nsps area
1 4 4
2 3 9
using tapply, it work:
> tapply(betarea1$nsps,betarea1$area,sum)
4 9 16 25 36 49 64 81 100 121 144
4 10 11 19 25 34 36 44 49 49 56
But i need it on a data.frame where the first line of this tapply result is
the area column and the second line is the nsps column.
Any idea for make this?
Thanks
Ronaldo
