SurvdigitizeR

The survdigitzerR package takes as input JPEG or PNG kaplan-meier curves and provides time of events. Time of events can be used as input to generate pseudo patient level data that resembles the data used to generate the kaplan-meier curve. The survdigitzeR package is currently under development.

Installation

You can install the released version of SurvdigitizeR from github.

# Install development version from GitHub
devtools::install_github("Pechli-Lab/SurvdigitizeR")

Or by opening the folder encompassing this project.

library(devtools)
install()

Example

This is a basic example digitizing the survival curve found in the vignettes folder.

library(SurvdigitizeR)
library(here)

survival_digitize(img_path = here("vignettes","KMcurve.png"),
                                  num_curves = 2,
                                  x_start = 0,
                                  x_end = 10,
                                  x_increment = 1,
                                  y_start = 0,
                                  y_end = 1,
                                  y_increment = 0.25,
                                  y_text_vertical =  T,
                                  censoring = F)

This R package was developed with the support of CADTH.
