No. Vincent Zoonekynd's Statistics with R is a separate guide by itself 
(and I hope to have more documents like this, translated into the Wiki). 
Apart from its translation into Wiki format (and perhaps, refreshment of 
the content to work with latest R version), this is not to be 
edited/merged with the rest.

The tips section starts with Paul Johnson's tips, but is dedicated to be 
a collection of many more tips, contributed by the Wiki users.

Guides and Tips are very different sections. However, it is possible to 
got some redundancy... a little bit like you have certainly redundancy 
in the various contributed packages and documents on CRAN, but you 
cannot force their authors for more coherence.

Best,
