? You can look into the edgeR vignette. To get the vignette type
'vignette("edgeR")' in the R command line. Also, just type
'vignette()'
and R will list all the vignette's for your loaded packages.? Vignettes
often have a model analysis that you can follow along and try to adjust
to your specific data. There is also Biostars,?
https://www.biostars.org/ . However, I doubt you will find anyone on an
online forum that will walk you through the whole analysis. Although,
there is probably only 10 plus or minus 4 commands for the whole analysis.
??? Alternatively, if you click on the URL you provided below, and at
the bottom of that page click on 'SRA Run Selector', scroll down a
little on the page you get to and select the runs you want to analyze by
checking the appropriate boxes, then click on the grey box on the right
that has the word 'Galaxy' in it, and it will load your selected runs
into an instance of Galaxy in which it is a little easier to analyze
data than on the R command line.
?? In the leftmost column of the galaxy page, scroll down to Genomics
Analysis and then click RNA-seq and scroll down a little and you will
see that edgeR is available. You will still have to learn a little about
edgeR analysis, so reading the vignette will be very helpful.
?? Also, for the comparisons you want to do, statistical help is
recommended.
