Add interval variable

add_interval_var() is an Add function that updates an object by adding new values to new or empty fields. Specifically, this function implements an algorithm to add interval variable. The function returns Updated data (a tibble).

Usage

add_interval_var(
  data_tb,
  id_var_nm_1L_chr = "fkClientID",
  msrmnt_date_var_nm_1L_chr = "d_interview_date",
  time_unit_1L_chr = "days",
  bl_date_var_nm_1L_chr = "bl_date_dtm",
  interval_var_nm_1L_chr = "interval_dbl",
  tmp_row_nbr_var_nm_1L_chr = "tmp_row_nbr_int",
  drop_bl_date_var_1L_lgl = F
)
