R help - Jun 2006 - NLME: using the layout option with the plot command

Hi
This is the 2nd time I am posting this question as I never got a reply the 
1st time round - apologies to anybody who might take offense at this but I 
dont know what else to do.

I am struggling to split up the plots of the grouped objects in nlme in a 
usable way. The standard plot command generates plots for each group on a 
single page. When there are many groups however this does not look so good. 
I have discovered the layout option which allows one to split up these plots 
over a certain number of pages but the problem is it very quickly scrolls 
through all the pages only leaving the final page in the viewer.

My question is how does one get to view all these pages? Or even better is 
there an option where the pages change only when prompted by the user?

Thanks

Greg

hi greg

If you are using windows, set up a plot window and click the "Record"
option in the menu. Then run the command. Now you can scroll back
through previous pages by hitting Page Up.

Beware that if you save your workspace without clearing the history,
you may have a lot of bloat from the graphs.

Hi Greg,

Since you haven't yet had a response, you could distill this.  It uses the
pixel dataset from nlme() as an example.

## To get separate files, do this
postscript("c:\MyGraph%03.ps", onefile=F)
plot(Pixel, display = "Dog", inner = ~Side, layout=c(4,1))
dev.off()

## To get your layout into one file, as separate pages, do this
postscript("c:\MyGraph.ps", onefile=T)
plot(Pixel, display = "Dog", inner = ~Side, layout=c(4,1))
dev.off()

If you prefer pdf, then use : pdf(filename, onefile=F), &c.  At the R prompt
do : ?postscript (and ?pdf), and go on reading!  Also have a look at setps() in
package Hmisc.

Regards,
Mark.
