Hi, Jim
Below is the code that I try and the result I obtained:
*br<-read.table("R_beginner_starter.dat",header=TRUE,sep="\t")
library(plotrix)
barp(t(br[,c(2,4)]))
*
The result generated:
http://r.789695.n4.nabble.com/file/n4468592/ScreenHunter_01_Mar._13_17.10.jpg
Which is different with my desired output bar graph :(
Do you have any idea to solve it out?
Thanks for advice.
