How to plot a blank plot

Hello everyone,

In plotting several graphics, I'd like to be able to plot a blank plot
as in:

par(mfrow=c(2,1))
plot(BLANK)
hist(rgamma(100000,6463.7,scale=0.015471),xlim=c(0,120),main="Emergence")

I realize screen allows me to do this, but I figure the functionality
must be there. Is there an equivalent to plot(BLANK)?

thanks,
adrian
