...1 0 0 1 2 And change the variables mapped in the previous plot: base <- ggplot(diamonds25, aes(fill = cut)) + geom_bar(position = "dodge") + opts(legend.position = "none") base + aes(x = cut) + facet_grid(. ~ color) I see all bars with height = 1. I have ovserved this problem (wrong bar heights, but not always = 1), in other cases when all counts are very small or zero. What's wrong here?

...mba version installed or any change in configuration. The time before the load went up to 5 or 10 but not more. Now at semester break only about 120 users are active at a time, during semester there are usually about 300 active users. But even these 300 users did not cause a load of 50, that I can ovserve now a peek times. Does anyone have a idea what might be going on here with these large number of machine ntlm auth tries suddenly?
