I am trying to apply the Reduce function with | (OR) and accumulate = TRUE on the columns of a matrix.

Example input:

m <- matrix(c(1,0,0,0,1,0,0,0,1), nrow = 3)

      [,1] [,2] [,3]
[1,]    1    0    0
[2,]    0    1    0
[3,]    0    0    1

The result should be

m2 <- matrix(c(1,0,0,1,1,0,1,1,1), nrow = 3)

      [,1] [,2] [,3]
[1,]    1    1    1
[2,]    0    1    1
[3,]    0    0    1

Tried it out, it works, thank you – scs Oct 10 '18 at 20:28
Please do not infer solutions from the structure of the matrix. I am interested in a general solution for a cumulative OR. – scs Oct 10 '18 at 20:58
