I am new to R and hope I can get some help here.
Say I have a matrix A as below
A<-[0 0 1, ->1st row
0 1 0, ->2nd row
0 0 1, ->3rd row
1 0 0] ->4th row
Now rows of A are considered to be factors, i.e. "001","010","100" in this
case. The output matrices B and C are desired,
B<-[001 2,->1st row
010 1,->2nd row
100 1]->3rd row

B=data.frame(table(B));
【在 D*******a 的大作中提到】
: data.frame(table(A))
