alpha	(1-alpha) is the approximate coverage probability for the confidence band.
main	title of the plot. The default is "Plot of Mean Residual Life and bounds".
ylim	the limits of the y-axis. The default is to include all points in the plotting range.
xlab	the label for the x-axis. The default is Time.
...	additional plotting options
