Sorry the data were all messed up. Let me try again.
Can anyone help me to plot a chart graph? I have a data set like this. I
would like a bar chart graph which mouse1's two treatments are clustered
together, so on.
I tried with barplot, but couldn't get it right.

Hi,
Can anyone help me to plot a chart graph? I have a data set like this. I
would like a bar chart graph which mouse1's two treatments are clustered
together, so on.
I tried with barplot, but couldn't get it right.
Hi Johnny,
Try this (assume your data frame is named "mp"):
# string the scores out in a vector
mpv<-as.vector(as.matrix(mp))
# make another two vectors specifying which score
# belongs to which mouse and which condition
# and combine these into a data frame
mp2<-data.frame(mpv,mouse=rep(c("M1","M2","M3"),each=20),
cond=rep(c("C","T","C","T","C","T"),each=10))
library(plotrix)
# make a list of colors for the bars
mc_colors<-list("lightgray",2:4,c("orange","brown"))
# display a clustered bar chart
barNest(mpv~mouse+cond,mp2,col=mc_colors,main="Mouse performance")
Jim
