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?
D.
