[R] plotting two histograms on one plot with hist function
I would like to plot two data sets (frequency (y-axis) of mean values for
0-1(x=axis)) on a single histogram for comparison. The hist() only allow the
overlay of two histograms, and although barplot() allows beside=TRUE, it does
not show frequency values (like hist) but rather all of the values. Is there any
way that I can use the hist() to plot two data sets similar to the barplot().
Any help or advice will be appreciated!
Kind regards,
Marguerite

[R] plotting two histograms on one plot with hist function
Why not just plot the two histograms on the same scale in a 2 panel plot?

Oh, I had not thought of it in those terms. It does make sense now.

I think OP request was "for comparison". Two panels may do, but why
not a
barplot of the histograms in the same panel ?
barplot( rbind(
hist(rbeta(30,2,4),breaks=seq(0,1,.1),plot=F)$counts,
hist(rbeta(30,6,8),breaks=seq(0,1,.1),plot=F)$counts),
beside=T)
see str(hist(yourdata)) or ?hist

Subject: RE: [R] plotting two histograms on one plot with hist function
Thank you for all the advice! After mailing the question, I actually found
a function called multhist (plotrix package) that plots two data sets (in
single list) on a single histogram.
Trust Jim to be there ahead of everyone!
The script is as follows:
#I listed to two data sets in ?long? format in a .csv file
input <- read.csv(file= "list.csv", h = TRUE)
library(plotrix)
#to plot two data sets on one histogram
multhist(input, xlab="Label?, ylab="Frequency",
col=c("Red", "Green"),
ylim=c(0,50))
#to add a legend to the top left corner
legend("topleft", c("Dataset
1","Data set 2"),
cex=0.6,bty="n", fill=c("Red","Green"))
Thanks again for the help!
