Arranging Multiple ggsurvplots

Description

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)

## Not run: 
# Arrange and save into pdf file
res <- arrange_ggsurvplots(splots, print = FALSE)
ggsave("myfile.pdf", res)

## End(Not run)
