d2 <- as.matrix(c(2,NA,4)) barplot(d2,beside=T) barplot(c(d2)) barplot(na.omit(d2)) d2[2,] <- 0 barplot(d2)
# So barplot is not "stopping" at the first NA (first 2 plots). But what does stacking even mean when you have a missing group in the middle ? you can't expect barplot to know... if you think it means 0 and the rest can just be stacked on top - define it that way.
