R help - Feb 2010 - scatterplots in car package

Hi, using scatterplot in 'car' package. 
There are 4 plots to be pictured together (ignore data used):

library(car)
par(mfrow=c(3,1))
ts.plot(rnorm(100))
ts.plot(rnorm(100))
scatterplot(rnorm(100),rnorm(100),boxplot="",smooth=T) # scatter with
non-parametric fit

problem is that the last one comes 'always' separate. 

Is there any way to solve it?? of course can use
fit=lm(rnorm(100)~rnorm(100)); plot(...);abline(fit), but I want to keep the
non-paramteric fit.

best regards, robert

Robert,

It seems that the scatterplot() command is starting a new graphics device.
You could use the base plot command to achieve the same results including
the non-parametric fit (scatterplot() uses a lowess fit):

#First it's important to save the distributions as objects, otherwise
rnorm() will produce a different set of values when you run the curve
fitting commands later.
x<-rnorm(100)
y<-rnorm(100)
plot(x,y,cex=0.7,col="red",xlab="rnorm(100)",ylab="rnorm(100)")
lines(lowess(y~x),col="red")
abline(lm(y~x),lty=2,col="red")

Dear Robert,

scatterplot() uses layout() to display the scatterplot along with the marginal
boxplots, and can't be used with par("mfrow"); scatterplot is
meant primarily for data analysis, not really for making presentation graphs.

Regards,
 John
