lines.mvna: Lines method for 'mvna' objects

In mvna: Nelson-Aalen Estimator of the Cumulative Hazard in Multistate Models

Description

Lines method for mvna objects.

Usage

## S3 method for class 'mvna'
lines(x, tr.choice, col = 1, lty, conf.int = FALSE,
      level = 0.95, var.type = c("aalen", "greenwood"),
      ci.fun = c("log", "linear", "arcsin"), ci.col = col,
      ci.lty = 3, ...)

Arguments

x	An object of class mvna.
tr.choice	A character vector of the form c("from to", "from to") specifying which transitions should be displayed. By default, all the transition hazards are plotted.
col	A vector of colours. Default is black.
lty	A vector of line types. Default is 1:number of transitions.
conf.int	Logical. Indicates whether to display pointwise confidence interval. Default is FALSE.
level	Level of the confidence interval. Default is 0.95.
var.type	Specifies the variance estimator that should be used to compute the confidence interval. One of "aalen" or "greenwood". Default is "aalen".
ci.fun	Specifies the transformation applied to the confidence interval. Choices are "linear", "log", "arcsin". Default is "log".
ci.col	Colours of the confidence interval lines. By default, ci.col equals col.
ci.lty	Line types for the confidence intervals. Default is 3.
...	Further arguments for lines.

Examples

data(sir.adm)

## data set transformation
data(sir.adm) 
id <- sir.adm$id
from <- sir.adm$pneu
to <- ifelse(sir.adm$status==0,"cens",sir.adm$status+1)
times <- sir.adm$time
dat.sir <- data.frame(id,from,to,time=times)

## Possible transitions
tra <- matrix(ncol=4,nrow=4,FALSE)
tra[1:2,3:4] <- TRUE

na.pneu <- mvna(dat.sir,c("0","1","2","3"),
                tra,"cens")

plot(na.pneu, tr.choice = c("0 2"), conf.int = TRUE,
     col = 1, lty = 1, legend = FALSE)

lines(na.pneu, tr.choice = c("1 2"), conf.int = TRUE,
      col = 2, lty = 1)
