lines.TPmsm {TPmsm}

lines method for a TPmsm object

Description

lines method for an object of class ‘TPmsm’.

Usage

## S3 method for class 'TPmsm'
lines(x, tr.choice, col, lty, conf.int=FALSE, ci.col, ci.lty,
legend=FALSE, legend.pos, curvlab, legend.bty="n", ...)

Arguments

x

An object of class ‘TPmsm’.

tr.choice

Character vector of the form ‘c(“from to”, “from to”)’ specifying which transitions should be plotted. Default, all the transition probabilities are plotted.

col

Vector of colour. Default is black.

lty

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

conf.int

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

ci.col

Colour of the confidence bands. Default is col.

ci.lty

Line type of the confidence bands. 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. By default no box is drawn.

...

Further arguments for lines.

Value

No value is returned.
