I am following the Differential analysis of count data – the DESeq2 package vignette which is great, however when I come to and can produce heatmaps, however when i try a PCA plot i get the following error.
plotPCA(rld, intgroup=c("LesionScore", "Treatment")
Error in (function (classes, fdef, mtable) :
unable to find an inherited method for function ‘exprs’ for signature ‘"DESeqTransform"’
My data has been input as a matrix following the phyloseq DeSeq2 tutorial
I have found this link where someone has the same problem, however I tried the suggested fix and this didnt work for me
I have been using a mixture of install.packages() and biocLite(), do I need to go through and install all packages using bioLite()?
