[R] ggplot and boxplots

[Richard M. Heiberger]

It looks like your V3 is a factor.

testing_ggplot <- data.frame(
  V1=factor(c(256, 256, 256, 272, 272, 272)),
  V2=c("Disabled", "Disabled", "Enabled", "Disabled", "Enabled", "Enabled"),
  V3=681:686)

library(ggplot2)
ggplot(testing_ggplot, aes(V2,        V3 )) + geom_boxplot() +
facet_wrap( ~ V1) + labs(title="what you want")
ggplot(testing_ggplot, aes(V2, factor(V3))) + geom_boxplot() +
facet_wrap( ~ V1) + labs(title="what you are getting")
