Coerce variable to a different class
Coerce the input to a different class, with a warning. More reliable then
as, and supports coercion to multiple classes.
coerce_to(x, target_class, .xname = get_name_in_parent(x))
x |
Input to coerce. |
target_class |
The desired class of x. Multiple values allowed (see note). |
.xname |
Not intended to be used directly. |
The input x after attempted coercion to the target class.
If x does not already have the target class, a warning is given
before coercion.
The function will try and convert the x to each of the classes given
in target_class, in order, until it succeeds or runs out of classes
to try. It will first try and convert x using a dedicated
as.target_class function if that exists. If it does not exist, or
throws an error then coerce_to will try to use
as(x, target_class).
