[R] R 2.3.1 on Mac OSX: apply a function to 'dist()' ?

[Hans-Joerg Bibiko]

Dear Sarah,

many thanks for the hint.

Unfortunately my distance metric is more complex. For me it is not  
only important to know whether there is a change between rows but  
also to know where (which column) the change occurs and furthermore  
to know if there is a change in e.g. column 5 to look at column 144  
etc. in order to be able to calculate a kind of weighted distance  
matrix.
I doubt that it would be possible to decompose my metric into some of  
the common manipulations(?)

Albeit I had a look at the package ecodist (many thanks for that, now  
I can solve an other problem ;) ). Based on this mechanism of  
decomposing I will adopt this idea to prepare some subfunctions  
written in C which could be combined to solve a specific problem.  
Doing so other users can modify these a bit easier (I hope).

But nevertheless I still have a speed problem!

Best regards,

Hans
