Error in x$membership

Hi all,

I am trying to annotate my peak list using Camera. I get the following error on the first step:

> xsa <- xsAnnotate(xs=xset4,polarity="negative")
Error in x$membership : $ operator not defined for this S4 class

This error occurs on both R 3.1.3 and R 3.1.2

Some googling indicated that the issue is probably due to the using a newer version of R and of igraph 1.0.1. I've tried rolling back to previous versions of both R but have had issues.

Any suggestions?

Thank you,

Thank you. The solution at the very bottom of that thread worked. I hadn't seen that before.
