dumpPackages: Display information for given packages
Description
The APT Package Management system uses a data-rich caching
structure. This accessor function displays the information for
a set of packages matching the given regular expression. It
corresponds somewhat to apt-cache showpkg pkgname but
displays more information.
Usage
dumpPackages(regexp = ".")
Arguments
regexp
A regular expression for the package name(s) with a
default of all (".")
Value
A boolean is returned indicating whether or not the given
regular expression could be matched to source packages -- but the
function is invoked ' for the side effect of displaying information.
Details
Note that the package lookup uses regular expressions. If only a
single package is desired, append a single $ to terminate
the expression. Ier-cran-rcpp$ will not
return results for r-cran-rcpparmadillo and
r-cran-rcppeigen.
