Hi,
Can someone suggest an efficient way to substitute a vector/matrix
which contains 1's and 0's to P's and A's (resp.)?
x[x == 1] <- "P"
x[x == "0"] <- "A"
(I added the quotes around 0 on the second line because the first line
changed x to a character vector. This isn't necessary, "0" == 0 comes
out TRUE, but I think it is clearer.)
