Hi
I have a matrix that contains 1565 rows and 132 columns. All the observations
are either "0" or "1". Now I want to keep all the observations same but just
one change, i.e. whenever there is "1", the very next value in the same row
should become "1". Please see below as a sample:
>df
0 0 1 0 0
NA 0 1 1 0
0 1 0 0 NA
What I want is:
0 0 1 1 0
NA 0 1 1 1
0 1 1 0 NA
I shall be thankful for the reply.
Saba
