I want to transform the data by "tapply" to one dataframe. But I can not get
it.
For example:
> tst=tapply(point,pp,length)
> tst[1:10]
p1 p10 p100 p1000 p1001 p1002 p1003 p1004 p1005 p1006
1 5 1 8 6 5 8 7 4 4
> res=as.data.frame(tst) # I try to transform it
> res[1:10,]
p1 p10 p100 p1000 p1001 p1002 p1003 p1004 p1005 p1006
1 5 1 8 6 5 8 7 4 4
How to transfrom it like the following:
>res
point ind
1 p1 1
2 p10 5
3 p100 1
4 p1000 8
5 p1001 6
Thanks!
