I'm faced with a problem in the volcano plot of CummeRbund. As shown in following link, you could see that there are plenty of infinite dots on the borders and also on the bottom. Is there any method to avoid this problem?https://drive.google.com/file/d/0ByJ9Aiypgye9Vm50V3J5REJnclU/view?usp=sharing

I've checked some pages, but it doesn't work when I put "pseudocount=0.0001" argument in csVolcano function. 

Do you have any advice? Thanks!

Sincerely,

Simon
