[R] Error in y - ymean : non-numeric argument to binary operator

[Peter Langfelder]

This is a bit of a shot in the dark since I haven't used randomForest
in several years, but I seem to recall that running randomForest
through the formula interface was asking for trouble... Try not using
the formula interface and specify the x, y, xtest arguments directly.
