Error in x$membership October 18, 2015, 11:02:15 AM Hi all,I am trying to annotate my peak list using Camera. I get the following error on the first step:> xsa <- xsAnnotate(xs=xset4,polarity="negative")Error in x$membership : $ operator not defined for this S4 classThis 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,DF Quote Selected
