No default method is available at the moment.

Usage

add_CNSR(gg, ...)
# S3 method for ggsurvfit
add_CNSR(gg, shape = 3, size = 2, ...)
# S3 method for ggtidycuminc
add_CNSR(gg, shape = 3, size = 2, ...)

Value

Censoring symbols overlayed on a visR ggplot

Arguments

gg

A ggplot created with visR

...

other arguments passed on to the method to modify geom_point

shape

aesthetic of ggplot2 geom_point. Default is 3.

size

aesthetic of ggplot2 geom_point. Default is 2.

Examples

library(visR)

# Estimate KM curves by treatment group
survfit_object <- survival::survfit(data = adtte, survival::Surv(AVAL, 1 - CNSR) ~ TRTP)

## plot without confidence intervals
p <- visR::visr(survfit_object)
p

# add censoring to plot
p %>% visR::add_CNSR()

# change censor symbol shape
p %>% visR::add_CNSR(shape = 1)

# change size and shape
p %>% visR::add_CNSR(size = 4, shape = 2)
