## The following are the packages required for today's GSEA lab
## presented by Robert Gentleman.  Please verify that you have them
## installed by loading them using the library() function in R.  As
## long as no errors are reported, you have what you will need to
## work on the lab.

##  You can type in the commands below.  If you are connected to the
##  internet, you can save some typing by using source() (see below).


## If you have a network connection, copy/paste the following into an
## R session:

#     source("http://bioconductor.fhcrc.org/workshops/2006/BioC2006/labs/rgentleman/rg-lab-reqs.R")

## If you are _not_ connected to the net, type in the following.  

if ((R.version$major == "2") && (as.integer(R.version$minor) >= 3:3)) {
    cat("Detected up-to-date R version\n")
} else {
    stop("Sorry, your version of R is out of date.  Please upgrade to R 2.3.1\n")
}

cat("Checking for packages...\n")
