dot-check_not_jagged: Check that list elements do not have jagged (unequal non-1)...

In stbl: Stabilize Function Arguments

Check that list elements do not have jagged (unequal non-1) lengths

Description

Expected to be called after .check_all_named(), so names(x) is guaranteed to be non-NULL. Length-1 elements are excluded from the check because they recycle to any length in as.data.frame().

Usage

.check_not_jagged(
  x,
  x_arg = caller_arg(x),
  call = caller_env(),
  x_class = object_type(x)
)

Arguments

x	The argument to stabilize.
x_arg	⁠(length-1 character)⁠ The name of the argument being stabilized to use in error messages. The automatic value will work in most cases, or pass it through from higher-level functions to make error messages clearer in unexported functions.
call	(environment) The execution environment to mention as the source of error messages.
x_class	⁠(length-1 character)⁠ The class name of the argument being stabilized to use in error messages. Use this if you remove a special class from the object before checking its coercion, but want the error message to match the original class.

Value

NULL, invisibly, if the list is not jagged.
