Getting shapes from custom PCA coordinates

[aConar]

Hi everyone,

I am working with a PCA constructed from trajectory analysis using the geomorph package (based on a OutCoe ). I want to replicate this to a Momocs::PCA to reconstruct shapes at custom PCA coordinates. However, when I run Mommocs::PCA(x), I encounter the following error:

Error: ! The x argument of as_tibble() can't be missing as of tibble 3.0.0. Run rlang::last_trace() to see where the error occurred.

It appears that there might be an issue related to the tibble package version. I also tried using the as_PCA function as an alternative, but I received this error instead:

Error: C stack usage 7976916 is too close to the limit

I would appreciate any help or suggestions on how to resolve these issues.

Thank you, Alej

Hi there, you can pass an arbitrary data.frame of positions to pos.shp in plot_PCA Hth V

Hi everyone,

I have a PCA morphospace constructed from trajectory analysis using the geomorph package, based on outlines processed with Momocs. I would like to know if it is possible to obtain outlines from custom coordinates in this morphospace.

Thank you in advance,

Alej
