Clear package options — drain • potions

Clear options of previously specified content. In most cases, calling drain with no arguments will be sufficient, but the arguments .slot and .pkg, and their corresponding functions drain_interactive() and drain_package() are provided in case greater control is needed. This is rarely needed for packages, but it is possible to manually specify the use of multiple slots when using potions::brew() interactively.

Usage

drain(.slot, .pkg)

drain_package(.pkg)

drain_interactive(.slot)

Arguments

.slot: (optional) slot to clear from options()
.pkg: (optional) package to clear from options()

Value

This function never returns an object; it is called for its' side- effect of removing data from options().

Details

Note that this function is not vectorized, so passing multiple values to .slot or .pkg will fail (e.g. drain(.slot = c("x", "y"))). Similarly, passing arguments to both .slot and .pkg will fail.
