ggplot Barplot Change size of ONE bar only

Question

I am building a very simple barplot with ggplot with multiple factors. One of the factor is missing (so cannot be plotted as I just don't have any data for it), no big deal but it leads to one of the bar being way bigger than the others.

Is there any way to either reduce the size of this particular bar or just avoid plotting it bigger from the start?

ggplot(data=tgc, aes(x=caste, y=dct,fill=treatment)) +  
  geom_col(width=0.7,position=position_dodge(width=0.8)) + 
  geom_errorbar(aes(ymin=dct-se, ymax=dct+se),width=.2,position=position_dodge(.8))+
  theme_bw()+
  scale_fill_manual(values=c("orangered2", "dodgerblue"))+
  theme(axis.line = element_line(colour = "black"),
      panel.grid.major = element_blank(),
      axis.title.x=element_blank(),
      axis.title.y=element_blank(),
      panel.grid.minor = element_blank(),
      panel.border = element_blank(),
      panel.background = element_blank())

Thanks a lot, yes this was exactly what I was looking for. I agree this is probably a duplicate question, I never found this link! — user3188922, Feb 05 '19 at 09:39
BTW for those who don't know, it seems that position_dodge2 is better and preserve the bar centre location — user3188922, Feb 05 '19 at 09:40

Transform it before you plot it. If you apply a log on the measurement variable, the differences among the plots will be reduced.
