Unload a package

This function attempts to cleanly unload a package, including unloading its namespace, deleting S4 class definitions and unloading any loaded DLLs. Unfortunately S4 classes are not really designed to be cleanly unloaded, and so we have to manually modify the class dependency graph in order for it to work - this works on the cases for which we have tested but there may be others. Similarly, automated DLL unloading is best tested for simple scenarios (particularly with useDynLib(pkgname) and may fail in other cases. If you do encounter a failure, please file a bug report at http://github.com/r-lib/pkgload/issues.

Usage
unload(package = pkg_name(), quiet = FALSE)
Arguments
package

package name.

quiet

if TRUE suppresses output from this function.
