The syntax rep(x, c(100,15)) is legal: it says to repeat the first value 100 times, the second 15 times. I try the line above and it works with no error. SNN is not telling us something, but I don't know what. Perhaps the content of data is relevant, or the content of his/her workspace, or whatever.
