Hi everybody,

New MAIT user but a seriously pleased one. What a game changer for my projects ... !

However, when few months ago, the full script was working OK, now I can't pass the PlotPLS and PLSModel lines.

This results in a 0kb graph file in the PLSScore plots folder with the following error message:

"Error: Please use column names for `x`"

I've tried, with my basic R knowledge, but can't figure out where this is from.

Anyone here having the same issue ? Any tips for fixing this ?

Many thanks !

Thomas
