Usage

renumber_time_id_tt(
  df,

  time_id_var = NULL,
  diagdat_var = NULL,
  timevar_max = Inf
)

Value

df

Arguments

df

dataframe

new_time_id_var

Name of the newly calculated variable for time_id. Required.

dattype

can be "zfkd" or "seer" or NULL. Will set default variable names if dattype is "seer" or "zfkd". Default is NULL.

case_id_var

String with name of ID variable indicating same patient. E.g. case_id_var="PUBCSNUM" for SEER data.

Numeric; default Inf. Maximum number of cases per id. All tumors > timevar_max will be deleted.

Examples

data(us_second_cancer)
us_second_cancer %>%
 #only select first 10000 rows so example runs faster
 dplyr::slice(1:10000) %>%
 msSPChelpR::renumber_time_id_tt(new_time_id_var = "t_tumid",
                             dattype = "seer",
                             case_id_var = "fake_id")
