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 is for CCHS cycles (2005-2007) that use COPD & Emphysema as separate variables, as well as Bronchitis. Asthma is used across CCHS cycles as a separate variable.
resp_condition_fun2(DHHGAGE_cont, CCC_91E, CCC_91F, CCC_91A, CCC_031)a categorical variable (resp_condition_der) with 3 levels:
respondent is over the age of 35 and has a respiratory condition
respondent is under the age of 35 and has a respiratory condition
respondent does not have a respiratory condition
# Using resp_condition_fun2() to create values across CCHS cycles
# (2005-2007) resp_condition_fun2() 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.
