If x and y are categorical variables, you should tell R so (i.e.,
convert to a factor) and if both should have the same categories (i.e.,
levels) you can supply this information as well:
R x - factor(x, levels = 2:5)
R y - factor(y, levels = 2:5)
Then, table() knows which categories to use:
R rbind(x = table(x), y = table(y))
2 3 4 5
x 0 6 4 0
y 4 0 1 5
and also the barplot() call given above will do the right thing.

Hi, I have two catagorical vectors like this; x = c(1, 2, 4, 2, 1) y = c(2, 4, 2 ,4, 1) I want to set up a barplot with the catagories 1-4 horizontally and number of occurances vertically for each vector x,y. I've tried boxplot(table(x,y), beside=T) and boxplot(c(x,y), beside=T) among others, but can't get it to work...Any ideas? I'd apppreciate any help __ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html

Ups, it should of course be barplot() in my mail, not boxplot:-) Kevin Wang wrote: Hi, T Petersen wrote: Hi, I have two catagorical vectors like this; x = c(1, 2, 4, 2, 1) y = c(2, 4, 2 ,4, 1) I want to set up a barplot with the catagories 1-4 horizontally and number of occurances vertically for each vector x,y.

RE: [R] Barplot - Can't figure it out
barplot(matrix(c(x,y),ncol = 2),beside=T) Does this help ?barplot notes height: either a vector or matrix of values describing the bars which make up the plot. If 'height' is a vector, the plot consists of a sequence of rectangular bars with heights given by the values in the vector. If 'height' is a matrix and 'beside' is 'FALSE' then each bar of the plot corresponds to a column of 'height', with the values in the column giving the heights of stacked sub-bars making up the bar. If 'height' is a matrix and 'beside' is 'TRUE', then the values in each column are juxtaposed rather than stacked. -Original Message- From: T Petersen [mailto:[EMAIL PROTECTED] Sent: Friday, 18 February 2005 1:35 PM To: Kevin Wang Cc: r-help@stat.math.ethz.ch Subject: Re: [R] Barplot - Can't figure it out Ups, it should of course be barplot() in my mail, not boxplot:-) Kevin Wang wrote: Hi, T Petersen wrote: Hi, I have two catagorical vectors like this; x = c(1, 2, 4, 2, 1) y = c(2, 4, 2 ,4, 1) I want to set up a barplot with the catagories 1-4 horizontally and number of occurances vertically for each vector x,y.

Re: [R] Barplot - Can't figure it out
Almost. Catagories aren't stacked - I would like to see that x has 2 instances of 1 while y has 1 instance of 1. What's more, there are now TWO distinct barplots - the left one shows x, while the right one shows y. I could live with that, but what I'd ideally want is to have x and y beside each other for EACH catagory - so for catagory 1 you could see taht there are more x's than y's (two x's versus one y).
