pkg_loadable


This function is like <code><a rd-options="" href="/link/require?package=crandalf&version=0.0.1" data-mini-rdoc="crandalf::require">require</a>()</code>, but it does not load the
package in the current R session. Instead, it launches a new R session to
test if a package is loadable. The reason for that is it is not trivial to
remove all the side effects brought by <code><a rd-options="" href="/link/library?package=crandalf&version=0.0.1" data-mini-rdoc="crandalf::library">library</a>()</code>, such as
DLL's. Instead of cleaning up everything, we just use a new R session to test
if a package is loadable.


For a given R package ready for release, all its reverse
dependencies are downloaded from CRAN and checked on Travis CI, to make
sure the current development version of this package does not break
packages that depend on it. For packages with a lot of reverse
dependencies, they can be divided into groups, with each group checked on a
separate Travis virtual machine to avoid Travis timeout. Additional system
dependencies (Ubuntu) can be manually specified in a configuration file.

This function is like <code><a rd-options='' href='require'>require</a>()</code>, but it does not load the
