Thanks in advance for any help I would like to plot a barplot with probability density instead of count frequencies, as is possible in histograms (freq=FALSE). Is this possible? I have tried the following code:
with(center,table(light))->light.table barplot(light.table ,col=brewer, freq=FALSE, beside=T) But freq=FALSE doesnt seem to work in the command of barplot. The reason why I want to use a barplot is that I have two variables. I have tried to use multhist instead, but when I plot the histogram the x-axis labels are unevenly spaced. I would like to create a bar with 7 ticks on the x-axis (1,2,3..7), however the following tics are yielded in the x-axis (1, 1.5, 2.5, 3.5, 4.5, 5.5, 6.5). How can I regulate this? I have used the following code: l<-list(m1=(center$light[center$site=="1"]), m2=(center$light[center$site=="2"])) multhist(l,breaks=c(1:7, by=1), freq=FALSE, main="Illumination in Plot Center", ylab="Density", col =brewer) I have tried names.arg= but this doesnt work in multihist either. Is there any way around this problem? Either by using barplot or multihist? I am very grateful for any help Honorata ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
