Hi,

I'm striving to use the screenFoodWeb function in the tRophicPosition package, and while creating a biplot, I was able to obtain a nice graph that clearly showed groups in different colors, but the legend was in black. Meanwhile, the following warning message appeared on the screen:

Use of `summary[[grouping[1]]]` is discouraged. Use `.data[[grouping[1]]]` instead.

Could anyone have encountered such a problem and found a solution? Please let me know.
