[R] Wrote new tiff package, would like big-endian tiffs for testing

 Do you know RGDAL(http://rgdal.sourceforge.net/) which can read Tiff files?

because I have implemented a package that reads tiffs and returns the image
data as a pixmap object (with additional slots for the original raw data
that has NOT be rescaled to 0-1 occurs in the pixmap data slots for
plotting).  I based the package on libtiff, not because it is perfect, but
because it is efficient and will allow access to a broad, even if not
comprehensive, range of tiff images. (By the way, one problem with libtiff
is that its TIFFReadRGBAImage function truncates 16 bit images to 8
bits...my library circumvents this path for 16bit images, thus maintaining
the full 16bit data--at least for non-tiled images).
