Hi all,

I am trying to create images in R suitable for journal publication. I'd
like to make an image that is 3.6" wide and 5.08" length, and 1200 dpi. 
When I create a tiff file that is 800 dpi and 4x4", it works (although
doesn't look good).
But when I create a tiff that is the size and dpi I want, it doesn't
work. I get the following error:

Error in tiff(filename = "C:\\Documents and
Settings\\sheppardj\\Desktop\\Manuscripts\\Figure 6c.tif",  : 
  unable to start tiff() device
In addition: Warning messages:
1: In tiff(filename = "C:\\Documents and Settings\\sheppardj\\Desktop\\
Figure 6c.tif",  :
  Unable to allocate bitmap
2: In tiff(filename = "C:\\Documents and Settings\\sheppardj\\Desktop\\
Figure 6c.tif",  :
  opening device failed

I've tried the same thing with jpeg, and still get the same error. I've
tried Cario, but I get an error that tiff bitmap is not supported.

Any help would be appreciated. Here is my code.
