Dear R-users,
I have some very simple data where 1's represent events and zeroes non-events,
e.g.
temp <- rbind(c(0,1,0,0,1,1,1,0), c(0,0,0,1,0,0,0,0))
For each row in the matrix, I would like to replace a singelton event by a 0.
That is, any 1 surrounded by zeroes (010) should be replaced by a zero (000).
Sequences of 1's should be left unchanged.
So the modified matrix shoud look like this:
00001110
00000000
How can I do this in R?
Thanks,
Stacey
