[BioC] proper way to handle small changes from different package versions

Hi Juliet,

It depends on what version of R you had installed at the time. Two years 
ago it would have probably been R-2.14.0 or so. You will really need to 
know which version of R you were using, as the lumi package version is 
tied to the R version.

Anyway, you don't say what OS we are talking about, but you want to go 
to one of these repositories

Linux:

http://cran.r-project.org/src/base/R-2/

Windows:

http://cran.r-project.org/bin/windows/base/old/

MacOS

http://cran.r-project.org/bin/macosx/old/

And install whatever version you think it might have been.

After installing, you can then just do

source("http://www.bioconductor.org/biocLite.R")
biocLite()
biocLite("lumi")


Best,

Jim
