Description

Checks if all arguments are of the same type.

Usage

assert_same_type(
  ...,
  .message = c("Arguments {.arg {arg_names}} must be the same type.", i =
    paste("Argument types are", paste0("{.arg ", arg_names, "} {.cls ", types, "}",
    collapse = ", "))),
  .class = "assert_same_type",
  .call = parent.frame()
)

Arguments

Arguments to be checked

.message

character vector passed to cli_abort(message) when assertion fails.

.class

character vector passed to cli_abort(class) when assertion fails.

.call

environment passed to cli_abort(call) when assertion fails.

Value
