R-2.8.0 : get platform device with get(getOption("device"))

Please do study the posting guide.  This was covered recently:

https://stat.ethz.ch/pipermail/r-devel/2008-April/049319.html
Nevertheless, perhaps an explicit NEWS entry could be warranted, 
something like

   o    The "device" option can now be a function, and is one in some 
standard setups. Consequentially, get(getOption("device")) will fail; 
programmers should usually use dev.new() instead.

Hi,

I have a R-package that works fine with R 2.7.0 (it builds, checks and
installs) but not with R 2.8.0.
There is no 'R 2.8.0' and will not be for some months.  You probably 
mean R-devel, but your code has been erroneous since R 2.5.0.

Running check in 2.8.0 gives the following output :
[...]
* checking examples ... ERROR
[...]
The error most likely occurred in:
[...]
dev <- show.pr(mr.tbl, col="green", type="b")
Error in get(getOption("device")) : invalid first argument
Calls: show.pr -> get
Execution halted

How can I change this code so that it works fine with R 2.8.0?

Thanks!
