When I enter "pkg describe -verbose image" I obtain a long list of

imfinfo
imapprox
rgb2ycbcr

roifill

What has happened to these functions - were they once in the package but
have been removed in the latest release? And if so, is there any way I
can obtain them?
Opps, that is in fact a bug in the "pkg describe -verbose" command. The
packages INDEX can perfectly well have function names in it that don't
exist. That was a deliberate choice so that it might be used to note
equivalent functions of matlab that Octave doesn't have, and in
particular note this in the function reference on the website. For
example see the roifill and roifilt2 functions on
http://octave.sourceforge.net/doc/image.html
Now the "pkg describe -verbose" command just uses this INDEX file as
well and prints out the contents. If the INDEX file was automatically
created by the "pkg install" command this is not a problem. However,
hand written ones like that for the image package aren't. Not sure of
the best solution for this, but note that the function reference section
of the octave-forge website is a better source for the type of
information you are looking for.
Cheers
David
