[R] adding the mean and standard deviation to boxplots

[Felipe Carrillo]

Tom:
You can do this with ggplot2. The code below puts  95%
CI,a smooth line and the mean(blue point)on the same
plot.

 library(ggplot2)
  r <- ggplot(ToothGrowth, aes(y=len, x=factor(dose)))
  r$background.fill = "cornsilk"
r + geom_boxplot(aes(colour=supp)) +
stat_summary(aes(group=supp),fun="mean_cl_normal",colour="red",geom="smooth",linetype=3,size=1)
+
  
stat_summary(aes(group=supp),fun="mean_cl_normal",colour="blue",geom="point",size=4)

   grid.gedit("label", gp=gpar(fontsize=10,
col="red")) # color the axis labels
