[R] Multiple lag.plots per page

[Gad Abraham]

Hi,

I'm trying to plot several lag.plots on a page, however the second plot 
replaces the first one (although it only takes up the upper half as it 
should):

par(mfrow=c(2,1))
a<-sin(1:100)
b<-cos(1:100)
lag.plot(a)
lag.plot(b)

What's the trick to this?

I'm using R 2.2.1 (2005-12-20 r36812) on Ubuntu Linux.

Thanks,
Gad
