dumpPackages {RcppAPT} | R Documentation |
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 (".") |
Details
Note that the package lookup uses regular expressions. If only a
single package is desired, append a single $
to terminate
the expression. Ie r-cran-rcpp$
will not
return results for r-cran-rcpparmadillo
and
r-cran-rcppeigen
.
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.
