Error with n_components=1 about umap

[tkonopka]

Thanks for the report.

In principle, it should be possible to use n_components=1. For example, it works on the iris dataset.

umap(iris[,1:4], n_components=1)

outputs

umap embedding of 150 items in 1 dimensions
object components: layout, data, knn, config

However, there are indeed cases where things break. For example,

umap(iris[1:5,1:4], n_neighbors=3, n_components=1)

outputs an error. I'll post an update...

Posted an update that fixes the bug (at least with the example with the iris dataset).

I'll take it the patch resolves the original question. But please re-open the issue if you encounter further issues.

Thanks again for reporting the bug.
