[R] Summarization

Hi All

I have a vector x containing 2 levels

x = c(1,1,1,0,0,0,0,1,1,0,0,0,1,1,0)

I would like to derive the following summarization

Level Count
1 3
0 4
1 2
0 3
1 2
0 1

I have generated an inelegant solution using lags and loops but feel sure
that there must be a better approach. If anyone has any thoughts I would be
very grateful if you would share them.

Thanks and best regards
