noob here
trying to make boxplots of some data
i would like to separate the boxplots according to conditons of various
levels
for example:

i have 
group:1 and 2, each group performed tests consisting of
condition A,B,C,D
side: left and right
time: 1 to 10

I would like separate boxplots of the results (x) of the tests (numeric) for
each group under each condition on each side over time.

so far i have set it up like this:
boxplot(test$x~test$time)
this gives me the plot for all vaues of x in each time bin.  basicaly i
would need a command that tells R to include only the data that agrees with
the group, condition, and side I set.
something like 
boxplot(test$x~test$time) where test$group=1,test$condition=A,test$side=left

can this be done?

Have a look at this: http://stats.stackexchange.com/questions/15486/plotting-a-boxplot-against-multiple-factors-in-r-with-ggplot2

Hope it helps.

Jos?

I am not sure I understand exactly what you want but does this do anything like what you want?

library(ggplot2)
mydata  <-  data.frame(result = rnorm(100), group = rep(c("1", "2"), each = 50), 
                       side = sample(c("L", "R"), 100, replace = TRUE) , dtime = rep(1:10, each=10))

p  <-  ggplot(mydata , aes( group, result, fill = side ))+ geom_boxplot() +
                            facet_wrap(~dtime)
p
