Hi everyone, 

I have a couple of bam files from RNAseq that I need to analyze.
I'm new to R world and so far I was able to install bioconductor and other packages for the analysis.
Could you guys give me links or tutorials including all the passages step by step, from the importation of bam files to how to make a differential expression analysis in R. 

I would appreciate your help 

thank you

How about this one?

Thank you for the useful links, 

I m following the first one, but when I try to import my external data "airway" package I have an error message.  

>  dir("bam files")
[1] "airway"              "Cell1.bam"          
[3] "Cell2.bam"           "RStudio-1.0.143.dmg"
> dir("airway")
character(0)
> indir <- system.file("extdata", package="airway", mustWork=TRUE)
Error in system.file("extdata", package = "airway", mustWork = TRUE) : 
  no file found

is it because I m not in the right directory?

Thanks 

Hello,  

I was able to reproduce the workflow in the first link, and I have a better idea about the passages needed for the RNAseq analysis.

I have a couple of small bam files that I'd like to compare, but I can not find a way to convert this bam file in a package so that can be analyzed in R. 
How can I create a library containing my bam files? I can not find any tutorial 

Can you help me with that? 

Thank you 

P
