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
