Hi, I'm running the example code for Time Course RNAseq experiments (section 4.8.8), and I'm getting the following error 'Error in dimnames(x$table) <- value : attempt to set an attribute on NULL' after running logCPM.fit <- cpm(fit, log=TRUE). How can I fix this error? Is there a step that wasn't included in the example?

Thanks,

New features are added regularly to edgeR and the documentation is updated accordingly. You are apparently reading the edgeR User's Guide that comes with current release of Bioconductor but running an older version of Bioconductor and the edgeR software.

The problem will be solved if you install the current release of Bioconductor (as advised in the Bioconductor Support posting guide). If you don't want to do that then you wound need to stick to the documentation that comes with the version of edgeR that you are using.
