Arranging Multiple ggsurvplots — arrange

Arranging multiple ggsurvplots on the same page.

Usage

arrange_ggsurvplots(
  x,
  print = TRUE,
  title = NA,
  ncol = 2,
  nrow = 1,
  surv.plot.height = NULL,
  risk.table.height = NULL,
  ncensor.plot.height = NULL,
  ...
)

Arguments

x: a list of ggsurvplots.
print: logical value. If TRUE, the arranged plots are displayed.
title: character vector specifying page title. Default is NA.
ncol, nrow: the number of columns and rows, respectively.
surv.plot.height: the height of the survival plot on the grid. Default is 0.75. Ignored when risk.table = FALSE. 1-risk.table.height - ncensor.plot.height when risk.table = TRUE and ncensor.plot = TRUE
risk.table.height: the height of the risk table on the grid. Increase the value when you have many strata. Default is 0.25. Ignored when risk.table = FALSE.
ncensor.plot.height: The height of the censor plot. Used when ncensor.plot = TRUE.
...: not used

Value

returns an invisible object of class arrangelist (see marrangeGrob), which can be saved into a pdf file using the function ggsave.

Examples


# Fit survival curves
require("survival")
fit<- survfit(Surv(time, status) ~ sex, data = lung)

# List of ggsurvplots
require("survminer")
splots <- list()
splots[[1]] <- ggsurvplot(fit, data = lung, risk.table = TRUE, ggtheme = theme_minimal())
splots[[2]] <- ggsurvplot(fit, data = lung, risk.table = TRUE, ggtheme = theme_grey())

# Arrange multiple ggsurvplots and print the output
arrange_ggsurvplots(splots, print = TRUE,
  ncol = 2, nrow = 1, risk.table.height = 0.4)


if (FALSE) { # \dontrun{
# Arrange and save into pdf file
res <- arrange_ggsurvplots(splots, print = FALSE)
ggsave("myfile.pdf", res)
} # }
