Usage

filter_schedule(
  schedule,
  subject_pattern = NULL,
  instructor_pattern = NULL,
  college_pattern = NULL,
  department_pattern = NULL,
  program_pattern = NULL
)

Value

A filtered data frame of matching courses.

Arguments

schedule

A data frame containing the course schedule with required columns: INSTRUCTOR, SUBJ. Optional columns include: COLLEGE, DEPARTMENT, PROGRAM.

subject_pattern

Optional regex pattern to match subject codes (e.g., "CSCI", "^MATH").

instructor_pattern

Optional regex pattern to match instructor names (e.g., "Smith", "^Jones").
