All,
I have:
x<- matrix(c(22,3,6,69,9,4,7,81,23,4,22,50),nrow=3,byrow=TRUE)
rownames(x)<- c("Cold or flu","Headache","Backache");
colnames(x)<- c("Went to doctor","No response","Did
nothing","Self-medicated")
x<- t(x)
print(x)
barplot(x,beside=TRUE,
ylim=c(0,90),
xlab="Ailment",
ylab="Percent",
legend.text=TRUE,
args.legend=list("topright",title="Treatment"))
abline(h=c(seq(10,90,10)))
box()
I'd like to get the horizontal lines in the background.
Any suggestions?
Hi David,
Try this:
library(plotrix)
barp(x,col=gray(c(0.2,0.4,0.6,0.8)),names.arg=colnames(x),
xlab="Ailment",ylab="Percent",ylim=c(0,90),
do.first=expression(abline(h=seq(10,80,10))))
legend(2.5,85,rownames(x),fill=gray(c(0.2,0.4,0.6,0.8)),
bg="white")
Jim
