Thank you all, a few ideas worked perfectly for me.
I take "with(dat1,aggregate(B,by=list(A=A),length))" for my task.
Have a nice day.

Hello,
Try the following.
dat <- read.table(text = "
A B
1 10-1 aaa
2 10-1 bbb
3 10-1 abc
4 10-2 vvv
5 10-3 ggg
", header = TRUE)
tbl <- table(dat$A)
data.frame(tbl)
Hope this helps,
Rui Barradas
