R help - Nov 2012 - dealing with different kinds of environmental data in one matrix

Hi,

I have done a CCA with an environmental data matrix including both relative
abundance of plant species, soil properties (continuous, with different
units of concentrations), and factors that should explain my species
matrix.

Only after running the analysis have I realized that I should have done
some kind of transformation to standardize the relative abundance of plant
species and soil properties. Which transformation can I use for this case?
Is it possible to use these two different types of data in one matrix?

Thanks.
