R help - Jul 2010 - Modify the plotting parameters for Vennerable obj.

Dear List,

I would like to modify the settings for plotting a Vennerable object,  
but I don't know how...so if anyone has an idea I would be really  
graetfull.

best, Fabian

some R code to illustrate my problem:
####
library(Vennerable)

ven <- compute.Venn(Venn(SetNames=c("A", "B"),
Weight=c(0,111,106, 26)))

# now my problem is that whenever I plot the object, the plot appears  
in box, and for cosmetic reasons I would like to get rid of that.
plot(ven)
