Isomap nnType: Method error

[FedeClaudi]

Hey, thanks for this awesome package.

I'm trying to fit Isomap using nntype=KDTree from NearestNeighbors but I get a method error

The error line being NN = fit(nntype, X) here.

Any advice on how to get around this? Using brute force tree works but I'd like to find an easier solution.
Also, is there a way to pass an already fitted tree? I'd like to re-use the same tree across different analysis steps.

Thank you

You cannot use directly KDTree. Here is the wrapper:

ManifoldLearning.jl/misc/nearestneighbors.jl

Line 9 in 4568237

# Wrapper around NearestNeighbors functionality

I see, thank you. Perhaps its worth adding a warning in the docs, I took them to mean that you can just use any tree type from nearest neighbours!

Julia lets you carried away. I need to put a type check for AbstractNearestNeighbors there.
