R help - Jul 2010 - Java Heap Space Error while running kpca command

Hi All,

I'm trying to run a kernel principal component analysis on a corpus with
89769 text documents. I'm using the kpca command from the kernlab package.
Here is the code:

	output<-kpca(text, kernel=worddot(type="spectrum", length=1))

The problem is that when I run the kpca, it bails after only a few minutes,
generating the following error:

	Error in
.jcall(.jnew("opennlp/maxent/io/SuffixSensitiveGISModelReader",  :
	  java.lang.OutOfMemoryError: Java heap space

The openNLP package is a dependency for the kernlab package.

output<-kpca(text, kernel=worddot(type="spectrum", length=1))

I appreciate any help anyone can give!
