Saving models to relative path fails

[Ax3man]

When trying to save a UMAP model:

save_uwot(orange_UMAP, 'my_folder/orange_UMAP')

I get this error:

Error in file(tarfile, "wb") : cannot open the connection
In addition: Warning messages:
1: In normalizePath(dirname(filename)) :
  path[1]="my_folder": No such file or directory
2: In file(tarfile, "wb") :
  cannot open file 'my_folder/orange_UMAP': No such file or directory

Changing to:

save_uwot(orange_umap, uwot:::abspath('my_folder/orange_UMAP'))

resolves the issue, suggesting that it is an issue with relative paths.

I think the issue stems from:

uwot/R/uwot.R

Lines 3960 to 3961 in fd5f337

	setwd(mod_dir)
	tmp_model_file <- abspath(file)

The absolute file path is computed after the change of working directory. Swapping these two lines fixed the issue for me.

Thank you for the report @Ax3man. And also for specifying the fix. for which I have made you a contributor in the DESCRIPTION. This should be fixed in master. I don't know when I will next attempt a new submission to CRAN though.

Much appreciated!
