Check if a Processing Step has been Applied

Scans an object's processing history to determine if a step with a specific name has already been performed. This is useful for preventing redundant operations or for enforcing a required order of preprocessing steps.

Usage

has_step(object, step_name)

Arguments

object

An S4 object containing a processing slot (list).

step_name

A character string specifying the unique name of the step to check for (e.g., "log2_transform").

Value

A logical value: TRUE if a log entry with the given step_name exists in the object's history, FALSE otherwise.
