[R] relative euclidean distance

[Sarah Leclaire]

Hi,

I would like to calculate the RELATIVE euclidean distance. Is there a 
function in R which does it ?

(I calculated the abundance of 94 chemical compounds in secretion of 
several individuals, and I would like to have the chemical distance 
between 2 individuals as expressed by the relative euclidean distance. 
Some compounds are in very low abundance whereas others are in high 
abundance, that's why I would like to correct for the abundance)

Thanks,
Sarah
