[R] its plot with pch-argument

[Mäkinen Jussi]

Hi mighty R-gurus and other enthusiastics,

I just encountered this:

library(its)
x <- its(sort(rnorm(10)), as.POSIXct(Sys.time() + 1:10))
plot(x, type = "p", pch = c(rep("A", 5), rep("B", 5)))

Am I missing something if I expect that all the points labeled as 'A' should be below all those labeled as 'B'? 

Thanks,

Jussi Mäkinen
