Seurat DimPlot generates a weird data frame together with the scatter plot

Question

[solo.albif]

Hi all, for some reason that I can not figure out, this code:

 # View UMAP with macrophages and patient clusters
macrophage_cells_patient_id_plot <- DimPlot(
  breast_cancer_patients_macrophage_cells,
  reduction = "umap",
  group.by = "Patient.ID",
)
macrophage_cells_patient_id_plot

which makes use of the Seurat function DimPlot, generates not only the scatter plot but also a data.frame:

I have used the DimPlot function in many other R scripts/Quarto documents and this never happened. Has anyone experienced this? Why is this happening? Is it connected to the reductions in the Seurat object? How can I get rid of the data frame?

It seems that the issue is related to the following discussion. Can you just run the DimPlot() code without assigning it to an object?

Yes, if I run DimPlot() without assigning to an object it works fine.

Thank you for the link to the RStudio issue! It did not come up during my searches.
