Talk:Hierarchical Cluster Analysis using QGIS and R

In the methods section referring to the selection of Ash trees, instead of going through a bunch of steps and then saying at the end that this doesn't always seem to work, perhaps introduce the fact that there are different possible methods at the beginning, with a short description of what they are, and then go through the two possibilities. Would cause less confusion for a new user who might start getting errors before they get to the part where you say you have had "mixed results" - i.e. warn them that there may be a crash/error, and if that happens you have another method "coming up"
