Dear Tom, I think you better switch to ggplot() instead of qplot().
library(ggplot2) dat <- expand.grid(id = 1:10, time = 1:3, group = 1:3) dat$Freq <- rnorm(nrow(dat), mean = dat$id * dat$time) ggplot(dat, aes(x = factor(time), y = Freq)) + geom_boxplot() + geom_jitter(aes(colour = factor(id))) But you can do it with qplot() qplot(factor(dat$time), dat$Freq, dat, geom = "boxplot") + geom_jitter(aes(colour = factor(dat$id))) IMO the ggplot version gives more readable code. Especially when you are doing complex plots. Splitting plots according to a factor is easy with facet_grid() or facet_wrap(). dat <- expand.grid(id = 1:10, time = 1:3, Group = 1:3) dat$Freq <- rnorm(nrow(dat), mean = dat$id * dat$time) ggplot(dat, aes(x = factor(time), y = Freq)) + geom_boxplot() + geom_jitter(aes(colour = factor(id))) + facet_grid(. ~ Group) If you want three different plots then you will need to do some reading on viewports, grobs and stuff. The ggplot2 book on Hadley's website give a good intro. HTH, Thierry ---------------------------------------------------------------------------- ir.

Is there away to do it? Also how can I put three plots on the same graph with ggplot2? mfrow=c(3,1) did not do the job. > dat group time id freq 1 1 00 0018 5.21 2 1 00 3026 3.13 3 1 00 5030 5.04 4 1 00 5108 3.23 5 1 00 5152 3.97 6 1 00 6080 0.16 7 1 01 0018 4.89 8 1 01 3026 6.58 9 1 01 5030 7.42 10 1 01 5108 10.10 11 1 01 5152 3.74 12 1 01 6080 0.81 library(ggplot2) qplot(factor(dat$time),dat$freq,dat,geom=c("boxplot","jitter"), ylab=names(dat[,4]),xlab="time") __________________________________________________________ Ta semester! - sök efter resor hos Kelkoo.
