Thanks Michael that works!
Now I am having a problem getting the results into a format I can use.
prop.table generates a contingency table that I tried to turn into a data
frame I could graph from with as.data.frame() however the results are not a
true data.frame. The rows have commas between some of the elements and
trying to look at a column results in the original contingency table being
displayed.
This is what I have:
pop <- matrix(1:100000)
groupIDs <- sample(pop,500)
groupVar <- sample(groupIDs,23000,replace=TRUE)
responseVar <- sample(1:5,23000,replace=TRUE)
example.data <- data.frame(groupVar,responseVar)
data.table <-
tapply(example.data$responseVar,example.data$groupVar,function(x){prop.table(table(x))})
example.data.frame <- as.data.frame(data.table)
But the example.data.frame object is not a true data frame, and I am not
sure how to get it into a format I can graph.
