resp_condition_fun1
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. 3 different functions have been created to account for the fact that different respiratory variables are used across CCHS cycles. This function is for CCHS cycles (2009-2014) that only use COPD and Emphysema as a combined variable. Asthma is used across CCHS cycles as a separate variable.
Usage
resp_condition_fun1(DHHGAGE_cont, CCC_091, CCC_031)
Arguments
DHHGAGE_cont |
continuous age variable. |
CCC_091 |
variable indicating if respondent has either COPD or Emphysema |
CCC_031 |
variable indicating if respondent has asthma |
Value
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

Examples
# Using resp_condition_fun1() to create values across CCHS cycles
# (2009-2014) resp_condition_fun1() 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.
