Dear list,
for a data structure like in df:
set.seed(100)
Treatment<-rep(c("Nitrogen","Carbon", "Sulfur"),each=9)
week<-rep(c(1,5,9),3,each=3)
genes<-rep(c("18s", "EF1b", "NR"),9)
copies<-rnorm(27, 1000000,400000)
df<-data.frame(Treatment,week,genes,copies)
i wrote this code for a xyplot:
library(lattice)
PLOT<-xyplot(data=df, copies~week|Treatment+genes,type=c("b","g"))
I would like to change PLOT in a way, that the strips for Treatment are
displayed only once at the top of each of the three columns. Additionally i
would like to strips for "genes" at the top of each panel.
I tried to adopt some code i found in the helplist using strip=function...
but i did not manage to get what i would like.
Can anyone give me advice?
Thanks,
Henning
