loadModules
is a function for creating multiple module
objects
from a specification sheet.
loadModules(fn, base_path = NULL, assessment_structure, examinee_list)
fn |
the full file path and name of a csv file containing module specifications. |
base_path |
(optional) the base path to be prepended to the file paths contained in the module specifications sheet. |
assessment_structure |
an |
examinee_list |
an examinee list from |
The module specification file is expected to have the following columns:
Grade
a string containing the grade in the form G?
, where ?
is a number.
Phase
a string containing the phase in the form P?
, where ?
is a number.
ItemPool
the file path of a file that contains item pool data. This must be readable with loadItemPool
.
ItemAttrib
the file path of a file that contains item attribute data. This must be readable with loadItemAttrib
.
PassageAttrib
the file path of a file that contains passage attribute data. This must be readable with loadStAttrib
.
Constraints
the file path of a file that contains constraints data. This must be readable with loadConstraints
.
a module list containing module
objects.
Each module can be accessed using module_list[[grade]][[test]][[phase]]
.
