Base Operator Check

Check if critical operators of R are not present in other packages or in the global env.

Usage

.base_op_check(error_text)

Arguments

error_text

Single character string used to add information in error messages returned by the function, notably if the function is inside other functions, which is practical for debugging. Example: error_text = " INSIDE <PACKAGE_1>::<FUNCTION_1> INSIDE <PACKAGE_2>::<FUNCTION_2>.". If NULL, converted into "".

Value

An error message if at least one of the checked operator is present in the R scope, nothing otherwise.
