In jrnold/r-checker: Data frames with column and table constraints

Description

An object containing column-level checks. The following constraint checks are implemented:

• class type

• uniqueness

• missing values

• list of arbitrary constraints

Usage

  ColumnChecks(classtype = "ANY", ...)

Arguments

classtype	Name of to class which the column must belong.
...	Data to be included in the object.

Objects from the Class

Objects can be created by calls of the form ColumnChecks(...).

Slots

classtype

character. Class type of object to be checked.

missings

logical. If FALSE, then no NA values are allowed in the object to be checked.

unique

logical. If FALSE, then duplicate values are allowed in the object to be checked.
