Re: [R] Barplot by two variables
Thanks for your solution, it worked perfectly, it was exactly what I wanted. I do have two more questions and hope you can help. I have another analysis exactly like the last one except it is done by month instead of year. When I graph it using barchart it makes the months go in alphabetical order. Is there anyway to change it so that the months go in the correct order (jan, feb, march, etc,). And how do I change the colors of the bars in the graph, they are weird colors and I want to change them. Thanks so much for your help. -Original Message- From: Deepayan Sarkar [mailto:[EMAIL PROTECTED] Sent: May 10, 2007 4:58 PM To: Spilak,Jacqueline [Edm] Cc: r-help@stat.math.ethz.ch Subject: Re: [R] Barplot by two variables On 5/10/07, Spilak,Jacqueline [Edm] [EMAIL PROTECTED] wrote: Hi all I have a bit of a problem.

Here's one solution using the lattice package: library(lattice) barchart(HSS ~ factor(Year), data = dataset, origin = 0, groups = Limit, auto.key = TRUE) And here is one using barplot(): DF Year Limit HSS 1 1999 ALT 0.675 2 1999 VFR 0.521 3 2000 ALT 0.264 4 2000 VFR 0.295 barplot(matrix(DF$HSS, ncol = 2), beside = TRUE, names.arg = unique(DF$Year), legend.text = unique(DF$Limit) Note that I convert DF$HSS to a two column matrix to enable using the built-in 'beside' argument in barplot() for the bar pairings, much like Deepayan has used the formula in barchart() above. Then it is a matter of getting the unique values for both the Years and the Limits to use them for the x axis labels and the legend text.
