The problem would appear to be in your data object, about which you give us no information. 1. There has been work on write.fit() recently. Try updating to the latest version from CRAN and see if the problem goes away. 2. In the latest versions of limma, you can also try write.table(fullfit, ...) 3. The problem is most likely that there is no component 'genes' in your 'fullfit' object. 4. If none of the above helps, include 'show(fullfit)' and state the version of limma that you are using.
