Description

Plot longitudinal data of an object of class jointdata, for a longitudinal variable. It is possible to plot all the subjects in the data set, or just a selected subset. See subset.jointdata.

Usage

"plot"(x, Y.col, type, xlab, xlim, ylim, main, pty, ...)

Arguments

x

object of class jointdata

Y.col

column number, or column name, of longitudinal variable to be plotted. Defaults to Y.col = NA, plotting all longitudinal variables

type

the type of line to be plotted, see plot for further details.

xlab

a title for the x-axis, see title.

xlim, ylim

numeric vectors of length 2, giving the x and y coordinates ranges, see plot.window for further details.

main

an overall title for the plot: see title.

pty

A character specifying the type of plot region to be used, see par for details.

...

other graphical arguments (see plot)

functions are useful to be used with this as lines and points

Examples

data(heart.valve)
heart.surv <- UniqueVariables(heart.valve, var.col = c("fuyrs", "status"), 
      id.col = "num")
heart.long <- heart.valve[, c(1, 4, 5, 7, 8, 9, 10, 11)]
heart.jd <- jointdata(longitudinal = heart.long, 
      survival = heart.surv, id.col = "num", time.col = "time")
plot(heart.jd, Y.col = "grad", col = "grey")
