Retrieve a set of tasks that can be completed in Dr Frost Maths, choosing tasks to include and exclude.
Arguments
- include
A character vector of tasks to include. If
NULL, all tasks will be included.- exclude
A character vector of tasks to exclude. If
NULL, no tasks will be excluded.
Value
A data frame with additional class 'dr_frost_tasks', where each row describes a task. The table has 4 variables:
- topic
The topic that the task falls under.
- subtopic
The subtopic of the task.
- task_name
The name of the task.
- description
A brief description of the task.
Details
If the include argument matches a topic, subtopic or task name of any task,
tasks will require a direct match with the string to be included. Otherwise,
partial matching/pattern recognition will be used to identify matches.
The same applies to the exclude argument.
While this makes specifying tasks simple most of the time, it can sometimes lead to some unexpected cases where more complex searches result in less matches.
