Simon,
I think this is what you are looking for.
###Random Data
crime <- sample(c('agree' ,'disagree'), replace=TRUE, size=100)
guns <- sample(c('agree','disagree'), replace=TRUE, size=100)
climate <- sample(c('agree', 'disagree'), replace=TRUE, size=100)
gender <- sample(c('male','both' ,'female'), replace=TRUE, size=100)
age <- sample(c('old', 'neither', 'young'), replace=TRUE, size=100)
dat <- as.data.frame(cbind(crime, guns, climate, gender, age))
rm(crime, guns, climate, gender, age)
opinion <-
rbind(
data.frame(table(dat[,4], dat[,1]), topic="crime", category="gender"),
data.frame(table(dat[,4], dat[,2]), topic="guns", category="gender"),
data.frame(table(dat[,4], dat[,3]), topic="climate", category="gender"),
data.frame(table(dat[,5], dat[,1]), topic="crime", category="age"),
data.frame(table(dat[,5], dat[,2]), topic="guns", category="age"),
data.frame(table(dat[,5], dat[,3]), topic="climate", category="age")
)
library(lattice)
barchart(Freq ~ Var1 | topic + category, groups=Var2, data=opinion,
stack=TRUE,
layout=c(3,2), scales=list(x=list(relation="free")))
