RShiny app problems about microviz HOT 2 CLOSED

Thanks for highlighting these issues.

• I was aware that problems can arise when specifying the shape. This error is emitted by the ggiraph package that microViz depends on to provide the plot interactivity. I will try to isolate why this happens for some shape specifications and not others, and see what I can do to avoid this limitation or at least work around it more cleanly.
• Regarding your points about the lasso not always being accurate, I have not seen this, but I will investigate :)
• Some of the options in the "Add:" menu are not expected to work with all ordination plots, and I should make this clearer in the documentation, or perhaps dynamically remove those options when they aren't applicable e.g.
  • taxa loadings cannot be drawn for distance-based ordinations
  • hulls and ellipses cannot be drawn without first mapping colour to a variable, to provide groups

I think I have resolved the issue with the shapes error (as far as is possible) in the latest development version. Since commit: c12e01f the user can select only variables with a max of 5 distinct levels (not including NA) for use as the shape mapping. A custom shape palette is now used which avoids using the composite shapes that were used by ggplot2 default and were causing the ggiraph dependency's error: Error: ids don't have the same length than str (most often, it occurs because of clipping)

I have also added a larger description of how to use the app to the ord_explore docs that might help somewhat with the other problems. Of course, please do let me know if you still have some issues with ord_explore.

I can't reproduce your experience of inaccurate lasso selection, what OS and web browser are you using? Is it selecting nearby points or completely incorrect points?
Thanks!
