Here is a step-by-step solution to the problem:

Step 1: Identify the issue

The issue appears to be that the labels in the faceted plot are overlapping or not being displayed correctly. This can happen when the layout of the plot is not properly managed.

Step 2: Examine the code

Take a closer look at the code used to create the faceted plot. In this case, the facet_wrap function is used with the scales = "free" argument, which allows for more flexibility in the arrangement of the panels.

Step 3: Adjust the layout

Try adjusting the layout of the plot by using different values for the pos argument in the gtable_add_grob function. For example:

gt1_r <- gtable_add_grob(gt1_r, gt_top2_r, t = 3, l = panel_id_top_r$l[2])

This sets the position of gt_top2_r to be at row 3, column 2.

Step 4: Add clipping

Try adding clipping to the plot by using the clip argument in the gtable_add_grob function. For example:

gt1_r <- gtable_add_grob(gt1_r, virg_grob, t = 3, l = panel_id_top_r$l[3], clip = "off")

This tells R to not clip the label at the edge of the plot.

Step 5: Verify the solution

Verify that the labels are now being displayed correctly and are no longer overlapping. If the issue persists, try further adjustments to the layout or clipping parameters.

The final answer is:

gt1_r <- gtable_add_grob(gt1_r, gt_top2_r, t = 3, l = panel_id_top_r$l[2])
gt1_r <- gtable_add_grob(gt1_r, virg_grob, t = 3, l = panel_id_top_r$l[3], clip = "off")
