resp_condition_fun2 | R Documentation |
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)
DHHGAGE_cont |
continuous age variable. |
CCC_91E |
variable indicating if respondent has emphysema |
CCC_91F |
variable indicating if respondent has COPD |
CCC_91A |
variable indicating if respondent has chronic bronchitis |
CCC_031 |
variable indicating if respondent has asthma |
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. library(cchsflow) resp2005 <- suppressWarnings(rec_with_table( cchs2005_p, c( "DHHGAGE_cont", "CCC_91E", "CCC_91F", "CCC_91A", "CCC_031", "resp_condition_der" ) )) head(resp2005) resp2007_2008 <- suppressWarnings(rec_with_table( cchs2007_2008_p, c( "DHHGAGE_cont", "CCC_91E", "CCC_91F", "CCC_91A", "CCC_031", "resp_condition_der" ) )) tail(resp2007_2008) combined_resp <- suppressWarnings(merge_rec_data(resp2005, resp2007_2008)) head(combined_resp) tail(combined_resp)
