Hello, I have a question about installing error of DESeq or DESeq2. 

Whenever I tried to install DESeq on my MAC OS X, such messages appeared. (Bold characters are what I typed.)

>biocLite('DESeq')

Error : Function found when exporting methods from the namespace ‘S4Vectors’ which is not S4 generic: ‘unlist’

Does anyone know why such error happened??

Thank you for your reading.

Your installed packages are out of sync, in particular BiocGenerics 0.17.3 is "too new". Best to install R from scratch, then use biocLite to install DESeq and its dependencies.

(Bioc release 3.2 goes with BiocGenerics 0.16: http://bioconductor.org/packages/3.2/bioc/html/BiocGenerics.html )
