Well, what about replacing 15 by something like 100?
The point is that you should look where MAX_LAYOUT_ROWS is used for 
calculations and whether there might result any problem after increasing it.

Looking into your mail header [telling us you are using Mozilla/4.0 
(compatible; MSIE 6.0; Windows NT 5.1; SV1)], I see you are using 
Windows and probably never have compiled R yourself (please read the 
posting guide which tells you to mention relevant information such as 
the OS in use).

Please read the file R/src/gnuwin32/Install.
It tells you how to compile R yourself and which tools are required.
