Ted,
I know how to do that. It's just such a standard display in SAS, SPSS
and Stata that I figured someone had done it and I had just overlooked
it.
Thanks!
Bob
I don't think there is a ready-made one, but it is very little
effort to make your own:
mkMyTable <- function(X){
Table <- data.frame( table(X) )
Table$Prop <- prop.table( Table$Freq )
Table$CumProp <- cumsum( Table$Prop )
Table
}
myTable <- mkMyTable(Score)
Hoping this helps!
Ted.
I think CrossTable in gmodels does what Bob is after:
CrossTable(gmodels) R Documentation
Cross Tabulation with Tests for Factor Independence
Description
An implementation of a cross-tabulation function with output similar to
S-Plus crosstabs() and SAS Proc Freq (or SPSS format) with Chi-square,
Fisher and McNemar tests of the independence of all table factors.
