[R] ggplot2 barplot in decreasing frequency

Hi all, I have a large data frame and would like to make a barplot of a categorical variable with the bars sorted in order of decreasing frequency. # Example: v1 = c(1.2, 1.4, 0.9, 1.0, 1.1, 1.0) v2 = c(aa, cc, bb, bb, cc, bb) v3 = c(8, 10, 11, 9, 9, 10) df = data.frame(v1=v1, v2=v2, v3=v3) #

Hi Morten Just order the factor the way you want before plotting: df$v2 - factor(df$v2, levels=c(bb, cc, aa)) p = ggplot(df) p + aes(v2) + geom_bar() Best, Ista On Wed, Oct 6, 2010 at 5:09 AM, Morten morten.lindb...@siv.no wrote: Hi all, I have a large data frame and would like to make a

Hi: Another approach is: v1 = c(1.2, 1.4, 0.9, 1.0, 1.1, 1.0) v2 = c(aa, cc, bb, bb, cc, bb) v3 = c(8, 10, 11, 9, 9, 10) df = data.frame(v1=v1, v2=v2, v3=v3) ggplot(df) + geom_bar(aes(x = reorder(v2, desc(v3 HTH, Dennis On Wed, Oct 6, 2010 at 2:09 AM, Morten morten.lindb...@siv.no wrote:
