Generates Kaplan-Meier survival plots for multiple projects or cohorts based on signature scores. Automatically determines optimal cutpoints for signature stratification and creates publication-ready survival curves.

Usage

batch_sig_surv_plot(
  input_pdata,
  signature,
  id = "ID",
  column_of_project = "ProjectID",
  project = NULL,
  time = "time",
  status = "status",
  time_type = "day",
  break_month = "auto",
  palette = "jama",
  cols = NULL,
  mini_sig = "score",
  save_path = file.path(tempdir(), "Multiple-KM-plot"),
  show_col = TRUE,
  fig_type = "pdf"
)

Arguments

input_pdata

Data frame containing survival data and signature scores.

signature

Character string specifying the column name of the target signature for survival analysis.

id

Character string specifying the column name containing unique identifiers. Default is `"ID"`.

column_of_project

Character string specifying the column name containing project identifiers. Default is `"ProjectID"`.

project

Character string or vector specifying project name(s) to analyze. If `NULL`, all projects are analyzed. Default is `NULL`.

time

Character string specifying the column name containing time-to-event data. Default is `"time"`.

status

Character string specifying the column name containing event status. Default is `"status"`.

time_type

Character string specifying the time unit. Options are `"day"` or `"month"`. Default is `"day"`.

break_month

Numeric value or `"auto"` specifying the interval for time axis breaks in months. Default is `"auto"`.

palette

Character string specifying the color palette. Default is `"jama"`.

cols

Character vector of custom colors. If `NULL`, palette is used. Default is `NULL`.

mini_sig

Character string for the signature label in the legend. Default is `"score"`.

save_path

Character string specifying the directory path for saving plots.

show_col

Logical indicating whether to display color information. Default is `TRUE`.

fig_type

Character string specifying the output file format (`"pdf"`, `"png"`, etc.). Default is `"pdf"`.

Value

Data frame containing combined survival analysis results from all projects.
