read_km_folder: Read many digitized Kaplan-Meier curves
In certara/survivalnma: network meta-analyses of survival data

Description Usage Arguments Details Value

The function reads a collection of files containing data from digitized Kaplan-Meier curves.

read_km_folder(
  path,
  preferred_baseline = NULL,
  filter = "KM.txt",
  split = "_",
  study = 1,
  outcome = 2,
  treatment = 3
)

`path`	path to a folder containing txt files from digitizing; each text file (corresponding to a Kaplan-Meier curve) should have 3 columns, in the following order: time, number at risk, number of events. Names of columns do not matter.
`preferred_baseline`	character; if you want to specify a preferred baseline treatment
`filter`	character; only files containing `filter` in title will be used
`split`	character; sign that separates study, outcome and treatment
`study`	integer explaining naming convention, see below
`outcome`	integer explaining naming convention, see below
`treatment`	integer explaining naming convention, see below

By default we assume that the files will follow naming convention such as study_outcome_trt_KM.txt, e.g. MOT_OS_Pazo_KM.txt. If the naming scheme is different, user can reorder at will or change the separation sign, e.g. for OS-Pazo-MOT-KM.txt we would say split = "-", study = 3, outcome = 1, treatment = 2.

Data frame which can be used as input into NMA models using survnma.
