R help - Jul 2010 - Grouping and stacking bar plot for categorical variables

Hi all,
I have a series of cateogiral variables that look just like this:

welfare=sample(c("less", "same", "more"), 1000,
replace=TRUE)
education=sample(c("less", "same", "more"), 1000,
replace=TRUE)
defence=sample(c("less", "same", "more"), 1000,
replace=TRUE)
egp=sample(c("salariat", "routine non-manual",
"self-employed,
farmers", "skilled labour, foremen", "unskilled
labour", "social and
cultural specialists"), 1000, replace=TRUE)

welfare, education and defence are responses to a series of questions  
about whether or not the respondent supports, less, the same or more  
spending on an issue.

egp is a class category.

What I would like is a barplot that is both stacked and grouped.  The  
x-axis categories should be the egp class category.  Within each class  
category I would like a cluster of stacked bars that show the  
distribution of spending support for each issue.

Can anyone suggest something?
Yours, Simon Kiss

Learn to search:

RSiteSearch("stacked barchart")

Once you are there you can also ask for prior years' r-help searching  
which will provide a large number of worked examples since this has  
been a frequently asked (and answered) question.

Hi Simon,
You might also like to look at the barNest function in the plotrix 
package, not stacked, but nested.
