In survCurve: Plots Survival Curves Element by Element

Description

This function adds a text label to the plot, which is preceded by a small identifier, similar to the function nrAtRisk.

Usage

survLable(
  text,
  x,
  y,
  font = 1,
  cex = 1,
  col.text = "black",
  len.flag,
  lty.flag = 1,
  lwd.flag = 1,
  bgcol.flag,
  lncol.flag = "black"
)

Arguments

text	String, content of the label.
x	A numeric value for the position at the x-axis.
y	A numeric value for the position at the y-axis.
font	Font of the label.
cex	Font size of the label
col.text	Color of the label.
len.flag	Length of the flag.
lty.flag	Line-typ of the flag. Value is 1 if not spezified.
lwd.flag	Line-wide of the flag. Value is 1 if not spezified.
bgcol.flag	Background-color of the flag (corresponding to the color of the confidence interval in the plot). No color if not value is specified.
lncol.flag	Color of the line of the flag. Default is "black".

Value

Draws the number at risk to an existing plot.

Examples

  require(survival)
  aml_model <- with(aml, survfit(Surv(time, status)~x))
  col1 <- adjustcolor("red",0.2); col2 <- adjustcolor("blue",0.2)
  survPlot(xmax=50)
  confIntArea(aml_model, col=col1, group=1)
  confIntArea(aml_model, col=col2, group=2)
  survCurve(aml_model, group=1)
  survCurve(aml_model, group=2, lty=2)
  survLable("maintain", 1, 0.2, bgcol.flag=col1)
  survLable("non-maint.", 1, 0.1, bgcol.flag=col2, lty.flag=2)
