<P><STRONG>Richard,</STRONG>
<P><STRONG>Many search engines, like Google, restrict matching to whole words. The word "R" does not occur nearly as frequently as the letter "R". </STRONG>
<P><STRONG>In fact, if you perform a Google-search using "R" as a search parameter, the very first article returned is "The R Project for Statistical Computing"!</STRONG>
<P><STRONG>I can estimate the density of this "R" concept: The query "R" returned 137,000,000 articles. How many articles are stored in Google? I can estimate this by searching for the word 'the', which according to Zipf, should occur in roughly 1 out of 2 documents. The "the" query returns 2,860,000,000 articles. </STRONG>
<P><STRONG>So, I estimate 5.72 giga-documents and the density of the word "R" (representing many concepts) is only 0.024 per document.</STRONG>
