He is not.  The latest version of rtiff was done by the CRAN team to 
fix a number of errors and keep it building on the CRAN platfoms -- 
you will see it was packaged by me.

It is very simple package, easy for you to modify -- this could be 
done in readTiff in a couple of minutes.

An alternative is BioC package EBImage (provided your ImageMagick 
installation supports TIFF).
