Determine vital status at end of follow-up depending on pat_status - tidyverse version

Description

Determine vital status at end of follow-up depending on pat_status - tidyverse version

Usage

vital_status(
  wide_df,
  status_var = "p_status",
  life_var_new = "p_alive",
  check = TRUE,
  as_labelled_factor = FALSE
)

Arguments

wide_df	dataframe in wide format
status_var	Name of the patient status variable that was previously created. Default is p_status.
life_var_new	Name of the newly calculated variable for patient vital status. Default is p_alive.
check	Check newly calculated variable life_var_new by printing frequency table. Default is TRUE.
as_labelled_factor	If true, output life_var_new as labelled factor variable. Default is FALSE.

Value

wide_df

Examples

#load sample data
data("us_second_cancer")

#prep step - calculate p_spc variable
