resp_condition_fun3: resp_condition_fun3

In cchsflow: Transforming and Harmonizing CCHS Variables

resp_condition_fun3

Description

This is one of 3 functions used to create a derived variable (resp_condition_der) that determines if a respondents has a respiratory condition. This function for CCHS cycles (2001-2003) that use COPD and Emphysema as a combined variable, as well as Bronchitis. Asthma is used across CCHS cycles as a separate variable.

Usage

resp_condition_fun3(DHHGAGE_cont, CCC_091, CCC_91A, CCC_031)

Arguments

DHHGAGE_cont	continuous age variable.
CCC_091	variable indicating if respondent has either COPD or Emphysema
CCC_91A	variable indicating if respondent has chronic bronchitis
CCC_031	variable indicating if respondent has asthma

Value

a categorical variable (resp_condition_der) with 3 levels:

1. respondent is over the age of 35 and has a respiratory condition

2. respondent is under the age of 35 and has a respiratory condition

3. respondent does not have a respiratory condition

Examples

# Using resp_condition_fun3() to create values across CCHS cycles
# (2001-2003) resp_condition_fun3() is specified in
# variable_details.csv along with the CCHS variables and cycles included.

# To transform resp_condition_der, use rec_with_table() for each CCHS cycle
# and specify resp_condition_der, along with the various respiratory
# variables. Then by using merge_rec_data() you can combine
# resp_condition_der across cycles.
