abort_argument: Abort based on issues with function argument

In lvmisc: Veras Miscellaneous

Description

Create a custom error condition created with rlang::abort() with a - hopefully - more useful error message and metadata.

Usage

abort_argument_type(arg, must, not)

abort_argument_class(arg, must, not)

abort_argument_length(arg, must, not)

abort_argument_diff_length(arg1, arg2)

abort_argument_value(arg, valid_values)

Arguments

arg	A character string with the argument name.
must	A character string specifying a condition the argument must fulfill.
not	Either a character string specifying a condition the argument must not fulfill or the bare (unquoted) argument name. In the last case, the function evaluates the argument type (abort_argument_type()) or length (abort_argument_length()) and displays the result in the error message.
arg1, arg2	A character string with the argument name.
valid_values	A character vector with the valid values.

Value

Each function returns a classed error condition. abort_argument_type() returns a error_argument_type class, abort_argument_length() returns a error_argument_length class, abort_argument_diff_length() returns a error_argument_diff_length class and abort_argument_value() returns a error_argument_value class.
