  sort = FALSE,
  decreasing = TRUE,
  add_all = FALSE,
  add_caption = TRUE,
  verbose = TRUE,
  headings = list(variable = "Group", n = "N", measure = "Hazard ratio", ci = NULL, p =
    "p"),
  ...
)

Arguments

data	a data.frame containing variables, time and os status.
grp_var	a group column.
covariate	a covariable for cox analysis.

add_caption	if TRUE, add caption to the plot.
verbose	if TRUE, print extra info.
headings	a list for setting the heading text.
...	other arguments passing to forestmodel::forest_model().

Value

a list.

Examples

library(survival)
ezcox_group(lung, grp_var = "sex", covariate = "ph.ecog")

p <- ezcox_group(lung,
  grp_var = "sex", covariate = "ph.ecog",
  controls = "age", add_all = TRUE
)
