HI,
Below is third example.
# here we want the full scale from zero to one
color.legend(2,6,4,6.4,legend=c("100% guys","100% girls"),
rect.col=color.scale(seq(0,1,by=0.25),c(0.2,1),c(0.2,0.4),c(1,0.4)))
par(mar=c(5,4,4,2))
# use barp to display a multiple histogram
h1<-table(cut(rnorm(100,4),breaks=seq(0,8,by=2)))
h2<-table(cut(rnorm(100,4),breaks=seq(0,8,by=2)))
h3<-table(cut(rnorm(100,4),breaks=seq(0,8,by=2)))
hmat<-matrix(c(h1,h2,h3),nrow=3,byrow=TRUE)
barp(hmat,names.arg=names(h1),width=0.45,col=2:4,
main="Multiple histogram using barp",xlab="Bins",ylab="Frequency")
legend(3.8,50,c("h1","h2","h3"),fill=2:4)
But it does not produce the plot that i need. Can u pls suggest me how to
use it to get stacked histogram for two series.
Ah, I didn't read the question carefully. I would use the "hist" function on both series and the plot the result with "barplot". firstone<-hist(rnorm(100))$counts secondone<-hist(rnorm(100))$counts barplot(rbind(firstone,secondone)) Jim
