survHE (version 2.0.5)

make.ipd: Create an individual level dataset from digitised data

Description

Piles in the simulated IPD resulting from running digitise for more than one treatment arm

Usage

make.ipd(ipd_files, ctr = 1, var.labs = c("time", "event", "arm"))

Arguments

ipd_files

a list including the names of the IPD files created as output of digitise

ctr

the index of the file associated with the control arm (default, the first file). This will be coded as 0

var.labs

a vector of labels for the column of the resulting data matrix. NB these should match the arguments to the formula specified for fit.models. The user can specify values. These should be 4 elements (ID, TIME, EVENT, ARM)

Examples

if (FALSE) {
# Defines the txt files to be used as inputs
surv.inp <- system.file("extdata", "survival.txt", package = "survHE")
nrisk.inp <- system.file("extdata", "nrisk.txt", package = "survHE")
# Runs 'digitise' to create the relevant output files
digitise(surv.inp, nrisk.inp, ipd_output = "IPD.txt")
# Now uses 'make.ipd' to create the pseudo-data
make.ipd("IPD.txt", ctr = 1, var.labs = c("time", "event", "arm"))
