tblcheck 0.1.0

• New package for inspecting data frames and vectors for grading with gradethis.
• Includes drop-in gradethis-style grading for tables and vectors that compare the student’s result with the exercies -solution:
  • grade_this_table() for automated grading of tables
  • grade_this_vector() for automated grading of vectors
• Additional, lower-level functions come in two variants, a grade function that returns a gradethis grade and a check function that returns a list detailing the differences between actual and expected output.
• Includes three general purpose checking functions:
  1. tbl_grade() and tbl_check() check that a tibble or data frame matches an expected output.
  2. vec_grade() and vec_check() check that a vector marches an expected output.
  3. tbl_grade_column() and tbl_check_column() check that a single column of a tibble or data frame matches an expected output (powered by vec_grade() and vec_check()).
• Includes six even more specific checking functions:
  1. tbl_grade_class(), tbl_check_class(), vec_grade_class() and vec_check_class() check that the class of an object matches that of an expected output.
  2. tbl_grade_dimensions(), tbl_check_dimensions(), vec_grade_dimensions() and vec_check_dimensions() check that the length, number of rows and columns, and number of dimensions of an object match that of an expected output.
  3. tbl_grade_groups() and tbl_check_groups() check that the groups of a table (created by dplyr::group_by()) match that of an expected output.
  4. vec_grade_levels() and vec_check_levels() check that the levels of a factor match that of an expected output.
  5. tbl_grade_names(), tbl_check_names(), vec_grade_names() and vec_check_names() check that the names of an object match that of an expected output.
  6. vec_grade_values() and vec_check_values() check that the values of a vector match that of an expected output.
• Also includes a number of functions for dealing with the problem output of check functions.
