Following from my previous questions, lag.plot doesn't recognise some of 
the standard plot variables, e.g. xaxt="n" doesn't remove the x-axis, 
and setting xlab causes an error:

 > lag.plot(sin(1:100), xlab="foo")
Error in plotts(x = x, y = y, plot.type = plot.type, xy.labels = 
xy.labels,  :
         formal argument "xlab" matched by multiple actual arguments

Is this a bug or a feature?

Also, how can I make lag.plot behave nicely when plotted with other 
plots on the same page? it takes up more room than it's allocated by 
par(mfrow).


Thanks for your help,
Gad
