Hi,
I would like to plot the following data such that each plot represents the
data from a single id and the plots are grouped according to the group
variable.
data<-data.frame(id=factor(rep(1:6,each=3)),
group=factor(c('a','a','b','c','c','c')),
x=runif(18,0,10),
y=rnorm(18,0,1))
The following ggplot nearly works but I would prefer to not plot the
missing combinations, i.e. each row will be a different length.
ggplot(data,aes(x=x,y=y))+geom_point(aes(color=group))+facet_grid(group~id)
Is this possible using ggplot or will I need to craft something using grid?
Thanks for any ideas.
Tom
