It's "horizontal", but I don't think this is coming from ks.test, which isn't supposed to do anything with graphics (unless you modified it). Would you by any chance have a graphics device open, for which you have been setting parameters?

Also, I think there is a buglet in which R warnings are sometimes delayed, so it may came from a previous command. I don't think it would happen twice, though.
