Hello,
	How can i increase the padding between the axis and the data  
region(box just containing the figure) in xyplot?

	An example:
	new <- function(x){ if(x<0){ return(x^2) }else{ return(x) } }
	x <- seq(-1,1,length.out=100)
	y <- sapply(x,new)
	sc=list()
	sc$alternating=0
	sc$tck=0

	xyplot(y~x,type='l',
	       aspect=0.05,
	       scales=sc,
	       col='black',
	       xlab='',
	       ylab=''
        )
	When plotted on quartz(Mac) device, there is very little padding  
between the bottom of the curve and the lower horizontal axis and  
between the maximum values of the curve and the upper horizontal axis.
	How can i increase the padding  - top,bottom,left and right?
	Thanks in advance for your time.
	Regards
