getPackages: Retrieve Names of All Installable Packages
Description
The APT Package Management system uses a data-rich caching
structure. This accessor function returns the names of installable
packages for a given regular expression.
Usage
getPackages(regexp = ".")
Arguments
regexp
A regular expression for the package name(s) with a
default of all (".").
Value
A data frame with columns containing the
package name and version (or NA if unavailable).
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.
