Hi,
for the data below:
time<-c(rep(1:10,5))
y<-time+rnorm(50,5,2)
subject<-c(rep('a',10),rep('b',10),rep('c',10),rep('d',10),rep('e',10))
group<-c(rep('A',30),rep('B',20))
df<-data.frame(subject,group,time,y)
I'd like to produce a plot with a single pannel with two loess curves one
for each group. the code below does that but on two different pannels, I'd
like to have both curves on the same pannel with different colors.
xyplot(y~time|group, groups=subject,
panel=function(...){
panel.loess(...)
}
,data=df)
