[R] mca-graphics: all elements overlapping in the help-example for multiple correspondence analysis

Dear all,  

I tried out the example in the help document for mca (the multiple correspondence analysis of the MASS package):  

farms.mca <- mca(farms, abbrev=TRUE)
farms.mca
plot(farms.mca)  

But the graphic that I get seems unfeasible to me: I cannot recognize the numbers (printed in black) because they are all overlapping and concealing each other. I don ´t dare using my own data, which consist of several hundred cases - I guess I won ´t see anything.  

How can I solve this? Thank you for any idea!  

Michael
