resp_condition_fun1: resp_condition_fun1

Description Usage Arguments Value See Also Examples

View source: R/respiratory-condition.R

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

1
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:

  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

# 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.
