In a boxplot - how can I prevent groups where the number of cases is less
than a set threshold from being plotted.
set.seed(42)
DF<- data.frame(type=sample(LETTERS[1:5], 100, replace=TRUE),
cost=rnorm(100))
count<- boxplot(cost ~ type, data=DF, plot = 0)
count$n
## how to only include plots where count$n> 18
boxplot(cost ~ type, data=DF)
Thanks in advance for any solutions.

DF <- data.frame(type = sample(LETTERS[1:5], 100, replace=TRUE),
cost = rnorm(100))
count <- boxplot(cost ~ type, data=DF, plot = 0)
for(i in c(1,3)) count[[i]] <- count[[i]][,count$n > 18]
for(i in c(6,2)) count[[i]] <- count[[i]][count$n > 18]
bxp(count)
