# libName: a vector of character string for the name of the library to be
# installed. Valid names include "all" - all the released packages,
# "affy" - packages "affy" plus exprs, "CDNA" - packages "CDNA" plus
# exprs, and "exprs" - packages "Biobase", "annotate", "genefilter",
# "geneploter", "edd", "Roc", and "tkWidgets".
# destdir: a character string for the directory where the downloaded
# packages will be stored.
# isDevel: a boolean indicating whether the released (FALSE) or
# developer (TRUE) version will be downloaded and installed.
# verbose: a boolean indicating whether any error related to the
# downloading process will be (TRUE) printed. Error messages will
# still be returned but invisible if berbose is set to FALSE.
# bundle: a boolean indicating whether packages will be downloaded as
# bundles (TRUE) or individual packages (FALSE). Valid bundle
# (e. g. "all", "exprs") or package ("tkWidgets", "annotate") have to
# be used in each case.
