[R] Postsript/Lattice interaction

[Kieran Healy]

Hello --

I'm using R-1.4.0 on a PC running SuSE Linux 7.1. Following Christian
Ritter's announcement this morning, I downloaded the new versions of
lattice and grid. I find that loading the lattice library causes
postcript() to include a blank first page when creating a file. Like
this:


> # Create regular postscript file of a plot
> postscript(file="anyplot.ps",horizontal=FALSE, paper="letter")
> plot(any.data)
> dev.off()

> # So far so good -- a one page plot.

> # Now load lattice library
> library(lattice)
  Loading required package: grid 
> 

> # Now try to plot again
> postscript(file="anyplot.ps",horizontal=FALSE, paper="letter")
NULL
> plot(any.data)
> dev.off()

Note the NULL output. The file "anyplot.ps" will now be two pages long
--- one blank page, then the proper plot. 

I'm not too familiar with lattice, so I'm not sure if this is a known
issue. A search through the help archives didn't turn anything up. 

Cheers,

Kieran
