VennDiagram Bugs

Dario Strbenac 
Hello,

Even though the documentation says that it is possible to have a scaled Euler diagram for three categories, this fails to happen. All of the circles are the same size.

My commands are :

library(VennDiagram)
A <- 1:10
B <- 9:18
C <- 15:500
venn.diagram(list(NameOne=A, NameTwo=B, NameThree=C), "example.tiff", euler.d = TRUE, scaled = TRUE, fill = c("red", "blue", "green"), cat.pos = 0)

I also notice that adjusting just one text label with cat.just = list(c(-1, 0), c(0, 0), c(0, 0)) actually moves all of them around. Why is that ?

Also, I have some real data I'm working on, where X, Y, Z are vectors of numbers. It has an error with an unhelpful error message. Can it be fixed ?
