### biocinstall() version 2.1.11
### Called by biocLite() when R version 2.6 is detected.
###
### Install Bioconductor packages using CRAN-style repositories.
### Arguments:
###
###   pkgs: character vector of Bioconductor packages to install.
###         The groupName argument will be ignored if pkgs is specified.
###
###   groupName: character matching one of "default", "affy", "graph", "lite",
###              "monograph", "all".
###
###   repos: the user should not try to pass this argument. It's in the argument list
###          of biocinstall() only because we want to raise an error when
###          the user tries to pass it.
###
###   dependencies: passed to install.packages (see install.packages documentation).
###
###   type: passed to install.packages (see install.packages documentation).
###
###   ...: extra arguments passed to install.packages (see install.packages documentation).
