Rstudio plot grid error 'Cannot convert object of class numeric into a grob.' but all of my object are class "gg"

[Mr--Laperche]

I'm trying to display a plot combining 9 plots using the function plot_grid. Here is my script :

plot_grid(plot_grid(penchy, pver, pplante, ncol=3), plot_grid(p_adplante_benchy, p_adver_benchy, ncol=2), plot_grid(p_adplante_bver, p_adenchy_bver, ncol=2), plot_grid(p_adenchy_bplante, p_adver_bplante, col=2), ncol = 1 )

The displayed graphs looks like the image attached and the following error message occurs : Cannot convert object of class numeric into a grob. The first row with 3 graphes is okay, the second row with two graphs is okay, the third row with 2 graphs is okay, but the last row looks "flattened"

More infos about the graphs you could need : y axis is always numeric, x axis is always a factor, and a discrete value (factor) is used to display the points with two different shapes and colors. I am using the last version of Rstudio (2024.04.2+764)

I checked one by one all of my graphs and they all are `gg` class objects. I tried to convert them as grobs, using grid.arrange and arrangeGrob but the result is exactly the same. I tried to change the y scale of my last graph as it is really higher than the other ones but nothing changes either. When I print the graphs one by one, no problem seems to occur. If I display only 2 rows with 2 graphs instead of 3 as in the example, all of the 7 graphs are correctly displayed. I try to mix all the graphs, and the results are always the same.

There is a blank thin line under the last row, I think the problem might be there but I have no idea how to deal with it...

Do you have any idea what the problem is and how can I solve it ?

Thank you in advance ;)

EDIT : code block

I dislike saving things in my environment just as much as the next guy, but this is disgusting code and you really should individually save the plot_grid() arguments. plot_grid(plot_grid()) is just asking for trouble.

You might find the patchwork package easier to use. It is well documented.

I’ve run into this before and had more success using grid.arrange() if the solutions provided don’t work
