plot.mvna {mvna}

Plot method for a mvna object

Description

Plot method for an object of class mvna. This function plots estimates of the cumulative transition hazards in one panel.

Usage

## S3 method for class 'mvna'
plot(x, tr.choice, xlab = "Time",
     ylab = "Cumulative Hazard", col = 1, lty, xlim, ylim,
     conf.int = FALSE, level = 0.95,
     var.type = c("aalen", "greenwood"),
     ci.fun = c("log", "linear", "arcsin"),
     ci.col = col, ci.lty = 3,
     legend = TRUE, legend.pos, curvlab, legend.bty = "n", ...)

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 plotted. Default, all the cumulative transition hazards are plotted.

xlab

x-axis label. Default is "Time".

ylab

y-axis label. Default is "Cumulative Hazard".

col

Vector of colour. Default is black.

lty

Vector of line type. Default is 1:number of transitions

xlim

Limits of x-axis for the plot

ylim

Limits of y-axis for the plot

conf.int

Logical. Whether to display pointwise confidence intervals. Default is FALSE.

level

Level of the pointwise confidence intervals. Default is 0.95.

var.type

A character vector specifying the variance that should be used to compute the pointwise confidence intervals. Choices are "aalen" or "greenwood". Default is "aalen".

ci.fun

One of "log", "linear" or "arcsin". Indicates which transformation to apply to the confidence intervals.

ci.col

Colour for the confidence intervals. By default, the colour specified by col is used.

ci.lty

Line type for the confidence intervals. Default is 3.

legend

A logical specifying if a legend should be added

legend.pos

A vector giving the legend's position. See legend for further details.

curvlab

A character or expression vector to appear in the legend. Default is the name of the transitions.

legend.bty

Box type for the legend.

...

Further arguments for plot method.

Details

This plot method permits to draw several cumulative transition hazards on the same panel.

Value

No value returned
