Hello, I was playing around with the newly implemented 'incomparables' argument in 'match' and realized the argument does not behave anything like I expected. Can someone explain what is going on here? Sorry if I'm misreading the documentation.
> match(1:3, 1:3, incomparables=1) [1] NA 2 3 # This seems right, the 1 in 'x' is 'incomparable' > match(1:3, 1:3, incomparables=2) [1] 1 2 3 # Shouldn't this be 1 NA 3? Why isn't the 2 incomparable? > match(1:3, 1:3, incomparables=5) [1] NA 2 3 # Why isn't the 5 ignored? Note from ?match: "incomparables: a vector of values that cannot be matched. Any value in x matching a value in this vector is assigned the nomatch value. For historical reasons, FALSE is equivalent to NULL." Thanks in advance!
