I'm struggling to get an LDA in Orange 3.28 (GUI).
The data, as you can see, is loaded as it should and has "iris" set as target (is it the same thing as class by the way, I could not find the info ?)
The linear projection widget works for PCA and circular :
instead, I get an error to the effect that "y should be a 1d array, got an array of shape (150,0) instead".
What do I do wrong, and how can I get a LDA ?
Bonus question: help says that "This widget displays linear projections of class-labeled data". However I could not find references to "class labeled data" in the manual. The closest I found is the "create class" widget, that creates apparently a new categorical variable based on text. Is this the same as a "target" variable ? The data table widgets refers both to "target with 3 values" (in this case) and allows to "color by instance classes" - is a class same as a target variable, then? If not how is a class defined?
