Hi all,

New to bioinformatics and am having trouble with RNAseq data analysis - namely alot of the packages recommended are 'not available for R version 3.4.2'
Is there a repository for the most up to date packages of limma and edgeR among others for example?

Thanks in advance

No, there isn't any problem with availability of packages. All the packages used in the limma or edgeR workflows are readily available for R 3.4.2 or 3.4.3. Just follow the installation instructions explained in https://www.bioconductor.org/install .

Briefly you start R, then type

source("https://bioconductor.org/biocLite.R")
biocLite("limma")
biocLite("edgeR")

etc.

This will install the latest versions of the packages.
