Unable to run umap with n_components = 1

[aftyh]

Hello!

I'm having some trouble running UMAP with one dimension due to an error that pops up saying

Error in optimize_layout_umap(head_embedding = embedding, tail_embedding = embedding,  : 
  Not a matrix.

I'm assuming that this is because the data being passed into the function is an atomic vector rather than a matrix due to it being one dimension? Perhaps this would be solved by using something like drop = FALSE or something similar?

Thank you.

Yes, it was along those lines. Thank you for reporting this. Should be fixed now.
