Source a student submission and return recorded objects — source_student

Sources a student R file from the current working directory and builds a robjgrader_records object from all new named objects of a recordable type that appear in .GlobalEnv after sourcing.

Usage

source_student_file(
  autograder_name = NULL,
  record_types = c("df", "ggplot", "model", "table")
)

Arguments

autograder_name: Character or NULL. Additional filename(s) to exclude beyond the auto-detected calling file. Default NULL.
record_types: Character vector of object types to capture. Any subset of c("df", "ggplot", "model", "table").

Value

A robjgrader_records object with a "student_file" attribute, returned invisibly.

Details

The calling script is automatically excluded from the candidate list — no manual autograder_name argument is needed in the typical case. Detection works both when the autograder is run via Rscript autograde.R (reads --file= from commandArgs()) and when it is loaded interactively via source("autograde.R") (walks sys.calls()). Pass autograder_name to add further exclusions.

The student file path is stored as attr(records, "student_file") and is available to code-inspection functions such as those in extract_code.R.
