Easiest way is probably to make grouprep a factor and insert a level
without observations such as in:
mydata$grouprep <- factor(mydata$grouprep, levels =
paste(rep(LETTERS[1:5], each=2), paste("grp", 1:2, sep="")))
beanplot(val~grouprep, data = mydata, ll = 0.04,
main = "example", ylab = "Size", xlab = "tank",
side = "both", border = NA,
col = list(c("blue", "white"), c("red", "yellow")))

Sorry for the previous error.
Dear Helpful R Users,
I am graphing some data using the beanplot, but I am having trouble
getting the output I desire. I have five tanks (A-E) and 2 groups for
each tank grp1 or grp2, except tank C where there is only grp1. (I only
changed the grouprep to "C grp1" for the example) When I plot them, I
would like A B C(only grp1 - half of the bean plot) then D and E (as
full beans). I assume there is some way to do this, but searching the
help archives, I haven't been able to find it.
I would also like to thank all of you, for your answers to others
questions, I have been gathering many useful tips.
# example
library(beanplot)
mydata <- data.frame(tank = rep(c("A","B","C","D","E"),
c(100,100,50,100,100)), group = rep(c("grp1", "grp2")), val = rnorm(450))
mydata$grouprep <- paste( mydata$tank, mydata$group)
mydata$grouprep <-with(mydata, ifelse((tank=="C"), "C grp1", grouprep))
beanplot(val~grouprep, data = mydata, ll = 0.04,
main = "example", ylab = "Size",
xlab = "tank",
side = "both", border = NA, col = list(c("blue", "white"), c("red",
"yellow")))
Thanks,
Jim
