Shows the external shared libraries that an installed R package is linked to
by running ldd
on the package so
file. Then uses system package manager
(e.g. dpkg
or rpm
or brew
) to locate which system package that contains
the binaries, headers, and (if available) sources for this library.
package_sysdeps(pkg, lib.loc = NULL)package_sysdeps_string(pkg, lib.loc = NULL)
package_links_to(pkg, lib.loc = NULL)
name of an installed R package
path to the R package directory for this package
For common distributions, the output also includes a URL to the distro-homepage of the system package. Here we can typically find more information about the package, such as configuration options, dependencies, and custom patches applied by your distribution.
Because we use ldd
, this only shows run-time dependencies of an installed R
package. This is especially relevant if you distribute the compiled R package
in binary form, because the same external libraries need to be available on
the user/deployment machine. This tool does not show dependencies that are
only needed at build-time, such as static or header-only libraries, and other
utilities required to build the package.
