koboquest: koboquest: Reading XLSForm questionnaires

In mabafaba/koboquest: Reads and understands kobo questionnaires

Description

For data collected with kobotoolbox, ODK or similar.

Details

This package lets you load a questionnaire and match it with the data. It then provides three main functionalities:

• identifying question types

• converting xml style data headers and values to labels

• parsing questionnaire skiplogic ('relevant' column in XLSForms.)

A questionnaire (in .csv format) is loaded globally with load_questionnaire. All other functions then refer to that questionnaire automatically. (See below on using multiple questionnaires in parallel.)

Identifying question types

• question_type is the standard function to determine data types.

There are functions for groups of types:

• question_is_categorical,

• question_is_numeric,

And for testing individual types specifically:

• question_is_select_multiple,

• question_is_select_one,

• question_is_sm_choice,

Parsing skiplogic

Use question_is_skipped To find out which records of a certain question were skipped

Using Multiple Quesitonnaires

If multiple questionnaires need to be used in parallel, you can store the output of link{load_questionniare} in an object. All other functions in this package are then available relating to that specific questionnaire as a list element of that object. Example:

# load the first questionnaire:
q1<-load_questionnaire(...)

question_is_categorical(...) # global functions now refer to q1
q1$question_is_categorical(...) # always refers to q1

# load the second questionnaire:
q2<-load_quesitonniare(...)
question_is_categorical(...) # global functions now refer to q2
q1$question_is_categorical(...) # always refers to q1
q2$question_is_categorical(...) # always refers to q2
