Hi! I am also having this error with plotArrow for splsda objects. Just wondering if there have been any fixes or work-arounds yet. Thanks!

Hi,

I am having an issue with this plot as well. Looking forward to the fixes.

For more information/context, I am following the MINT case study. Here are more details of the errors received when executing plotArrow(mint.splsda.res):

Error: Aesthetics must be either length 1 or the same as the data (125): x, y, xend and yend Run `rlang::last_error()` to see where the error occurred.

Executing rlang::last_error() yields the following:

<error/rlang_error>
Aesthetics must be either length 1 or the same as the data (125): x, y, xend and yend
