Hi, Please advice on what type of graph can be used to display the following data set. I have the following: Name ? ?Class a ? ? ? ? ? ? Class 1 a ? ? ? ? ? ? Class4 b ? ? ? ? ? ? Class2 b ? ? ? ? ? ? Class1 d ? ? ? ? ? ? Class3 d ? ? ? ? ? ? Class5 e ? ? ? ? ? ? Class4 e ? ? ? ? ? ? Class2 So each entry in name can belong to more than one class. I want to represent the data as to see where overlaps occur that is which names are in the same Class Name and also which names are unique to a Class. I tough a Venn Diagram would work but this can only present numerical values for each Class, I would like each name to be presented by a dot or *.
Assuming DF is the indicated data.frame: library(gplots) with(DF, balloonplot(Name, Class, rep(1, nrow(DF)), label = FALSE))
Here is one additional idea:
xt <- xtabs(~ Class + Name, DF)
symnum(xt, cutpoints = 0:2/2, symbols = c(".", "+"))
Name Class a b d e Class1 + + . . Class2 . + . + Class3 . . + . Class4 + . . + Class5 . . + .
