R help - Jul 2004 - error "evaluation nested too deeply" {was "Heatmap"}

Hi,

Trying to plot a large dendrogram, I get the recursion limit error


	Error in match.fun(FUN) : evaluation nested too deeply: infinite
recursion / options(expression=)?

 but setting

 	options(expressions = 10000)

or something large enough to solve the infinite recursion  limit
problem,


I get 

	Error: protect(): stack overflow


Is there anything that can be done?

Thanks

Claudio Donati
