Have a look at this example
h1 <- cut(rnorm(1000, 4), breaks = seq(0, 8, by = 2))
h2 <- cut(rnorm(1000, 3), breaks = seq(0, 8, by = 2))
h3 <- cut(rnorm(1000, 5), breaks = seq(0, 8, by = 2))
dataset <- data.frame(Set = rep(c("A", "B", "C"), each = 100), value = c(h1,
h2, h3))
dataset$fvalue <- factor(dataset$value)
library(ggplot2)
ggplot(dataset, aes(x = value, fill = Set)) + geom_histogram(binwidth = 1) +
xlim(1, 5)
ggplot(dataset, aes(x = fvalue, fill = Set)) + geom_histogram()

To call in the statistician after the experiment is done may be no more than
asking him to perform a post-mortem examination: he may be able to say what the
experiment died of.

Onderwerp: Re: [R] How to plot stacked histogram in R?
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.
Regards
