[R-sig-eco] 'grouping' grouping variable

[Jakub Szymkowiak]

Hello,
I have a problem and I don't know how can I solve it.
I have one grouping variable (16 regions in my country). Every region is 
described by several environmental variables, in example arable fields area, 
woodland area or meadows area.
I want to group this regions to small number of groups so that, the similar 
regions (in terms of my environmental variables) will be in the same group.
Any cues, how can I solve this?

Cheers,
Jakub
