Cumhazard.plot: Plot for Cumulative Hazard Function

Description

A function used to plot the curves of cumulative hazard function.

Usage

Cumhazard.plot(time,status,group,col=c(1,4),lwd=c(1,1),lty=c(1,1)
               ,lab.x="",lab.y="",legend=FALSE,local.x=NULL,local.y=NULL
               ,legend.0="",legend.1="")

Value

None

Arguments

time

The follow up time for right censored data.

status

The status indicator, normally 1=event, 0=alive or right censored.

group

The group indicator for comparison, and the elements of this vector must take either 0 or 1. Normally, 0= control group, 1= treatment group.

col

A vector of integers specifying colors for each group. The default value is c(1,4).

lwd

A vector of numeric values for line widths. The default value is c(1,1).

lty

A vector of integers specifying line types for each curve. The default value is c(1,1).

lab.x

Label given to the x-axis.

lab.y

Label given to the y-axis.

legend

An indicator variable for adding a legend. If it is present this implies legend=FALSE.

local.x

Changed the x-axis scale for the legend if legend=TRUE.

local.y

Changed the y-axis scale for adding a legend if legend=TRUE.

legend.0

Label given to the control group if legend=TRUE.

legend.1

Label given to the treatment group if legend=TRUE.
