Abstract
A scope is something functions or expressions are associated with that tells them what values variables refer to. It is used to figure out which environment expressions are evaluated in. The same variable name can be used many places in a program, but the scope of an expression tells R exactly which variable of a given name is referred to in the expression.
A significance statement is not available in the OpenAlex record.
A contribution statement is not available in the OpenAlex record.
Method details are not available in the OpenAlex metadata.
Findings are not separately available in the OpenAlex metadata.
Limitations are not available in the OpenAlex metadata.
Application details are not available in the OpenAlex metadata.
