count_event_by: funciton to count event, subgroup number inside TableSubgroupCox, TableSubgroupMultiCox

Description

Function to count event, subgroup number

Usage

count_event_by(
  formula,
  data,
  count_by_var = NULL,
  var_subgroup = NULL,
  decimal.percent = 1,
  data_original = NULL,
  formula_original = NULL
)

Arguments

formula	formula with survival analysis
data	same data as in formula
count_by_var	variables to count subgroup for
var_subgroup	1 sub-group variable for analysis,
decimal.percent	decimals to show percent of, Default: 1
data_original	Original data for competing risk analysis (before finegray transformation), Default: NULL
formula_original	Original formula for competing risk analysis (before finegray transformation), Default: NULL

Details

This function is used inside TableSubgroupCox, TableSubgroupMultiCox for calculation. When data_original and formula_original are provided, counts and percentages are calculated from the original data instead of the finegray-transformed data, ensuring accurate event counts in competing risk analysis.

Value

Table with event, subgroup number
