weights option for TableSubgroupMultiCox

[youmingmeia]

Hi prof. Jinseob Kim, thanks for your excellent work. The TableSubgroupMultiCox function in the jstable package has been extremely useful for my analyses, and I greatly appreciate the work you have put into developing it.
I am wondering if there are any plans to include a weight option within the TableSubgroupMultiCox function. This option would be very beneficial for analyses involving IPTW are necessary.

Currently, No coxph weight option in TableSubgroupMultiCox, But you can use weight with svydesign data. The below is example code (survey design)

library(survival)
library(dplyr)
lung %>%
  mutate(
    status = as.integer(status == 1),
    sex = factor(sex),
    kk = factor(as.integer(pat.karno >= 70)),
    kk1 = factor(as.integer(pat.karno >= 60))
  ) -> lung
TableSubgroupMultiCox(Surv(time, status) ~ sex,
  var_subgroups = c("kk", "kk1"),
  data = lung, time_eventrate = 100, line = TRUE
)

## survey design
library(survey)
data.design <- svydesign(id = ~1, data = lung)
TableSubgroupMultiCox(Surv(time, status) ~ sex,
  var_subgroups = c("kk", "kk1"),
  data = data.design, time_eventrate = 100
)
