[R] Help with Loading a Package

[Stephanie Cooke]

I am trying to use these commands to load a package:

library(Biobase)
 library(limma)
 library(drosEmbryo)
 data(drosEmbryoRMA)

The drosEmbryoRMA is .rda file. I have always loaded .txt files and I
have never heard of a .rda file and I can not figure out how to load
it. This file comes in a zip file. I am not sure if there is something
else that should be used in the zip file. The zip file is from this
website: http://www.bioconductor.org/workshops/2005/BioC2005/labs/lab01/drosEmbryo.html/view?searchterm=time
I would appreciate if anyone could help me with this.

Thanks,

Stephanie
