Arguments

x

an object of class burndown, to be plotted.

draw.regression

draw.lastupdate

boolean, set to TRUE to draw the last update (which otherwise requires a sharp eye).

t.stop

y.name

character string, for labelling the vertical axis.

debug

boolean, set to TRUE to monitor the work.

...
