KG2A

Change Color and Line Type in Kaplan-Meier Plot by Treatment Arm

The same setup as in KG1 is used.

Code

library(tern)
library(dplyr)

adtte <- random.cdisc.data::cadtte %>%
  df_explicit_na() %>%
  filter(PARAMCD == "OS") %>%
  mutate(is_event = CNSR == 0)

variables <- list(tte = "AVAL", is_event = "is_event", arm = "ARM")

The line color and line type in the plot can be customized using the col and lty arguments of g_km(), respectively. Note that the order of the levels of the treatment arm factor variable is matched with the order of the colors.

Code

g_km(
  df = adtte,
  variables = variables,
  annot_surv_med = TRUE,
  col = c("purple", "orange", "red"),
  lty = 5
)

Code
