I am trying to generate a boxplot whose data come from two scenarios. In the plot, I would like to group boxes by their names (So there will be two boxes per variable). I know ggplot would be a good choice. But I got errors which I could not figure out. Can anyone give me some suggestions?

Error:
"Error in unit(tic_pos.c, "mm") : 'x' and 'units' must have length > 0"
Update
Figure out the error. I should use geom_boxplot(aes( fill= factor(group)), width = 0.8) rather than fill= group
