plot.survtab: plot method for survtab objects

Description

Plotting for survtab objects

Usage

## S3 method for class 'survtab':
plot(x, y = NULL, subset = NULL, conf.int = NULL,
  col = NULL, lty = NULL, ylab = NULL, xlab = NULL, ...)

Arguments

x

a survtab output object

y

survival a character vector of variable names to plot; e.g. c("surv.obs","r.e2")

subset

a logical condition; obj is subset accordingly before plotting

conf.int

logical; if TRUE, adds any confidence intervals present in obj for variables in y

col

line colour; one value for each survival variable; will be recycled

lty

line type; one value for each survival variable; will be recycled

ylab

label for Y-axis

xlab

label for X-axis

...

additional arguments passed on to plot and lines.survtab; e.g. ylim can be defined this way

Examples

x <- lexpand(sire, fot=seq(0,5,1/12), status=status, pophaz=popmort)
st <- survtab(x)
plot(st, "r.e2")

plot(st, c("surv.obs", "r.e2"), conf.int=TRUE, col=1:2, xlim=c(0,5))
