Hi,
I have a data frame like this:
ScoreDoseSex
2.81Dose1M
1.81Dose1M
1.22Dose1M
0.81Dose1M
0.49Dose1M
0.22Dose1M
0.00Dose1M
-0.19Dose1M
-0.17Dose1F
-0.32Dose1F
-0.46Dose1F
-0.58Dose1F
-0.70Dose1F
-0.81Dose1F
-0.91Dose1F
-1.00Dose1F
-1.77Dose2M
-1.85Dose2M
-1.93Dose2M
-2.00Dose2M
-2.07Dose2M
-2.14Dose2M
-2.20Dose2M
-2.26Dose2M
-2.32Dose2F
-2.38Dose2F
-2.17Dose2F
-2.49Dose2F
-2.54Dose2F
-2.58Dose2F
-2.63Dose2F
-2.42Dose2F
I can make the dotplot using lattice package:
library(lattice)
dat<-read.table("test.txt",header=T,sep="\t")
dotplot(Score ~ Dose | Sex, groups=Sex, data=dat)
How can I add mean line and stdev bar around mean line to this dotplot?
I have searched maillists, only several post about add sth to dotplot, but they
are not what I want.
I know it may have sth to do with panel.function, but don't know how to
implement it.
I think the mean and stdev bar are popular additions to dot plot, don't know
why
there is no argument to control this kind of plotting.
Thanks.
Xiaokuan
