Hi, I want to make 3d surface plot, and I see a lot about "volcano" tutorial. I found that, in that "volcano" data frame is numeric matric. Later, I want to convert my "own" data frame into numeric matric by seeing your video. However, the "x1", "x2" and "x3" are still not converted. how to convert this title variable into numeric matric?? do you have any idea.

My data is showing the type as data.frame and when i try to convert to numeric it says "Error: 'list' object cannot be coerced to type 'double' . Please help?

[lihe]

mine is telling me:
Assigned data must be compatible with existing data.
x Existing data has 153 rows.
x Assigned data has 0 rows.
i Only vectors of size 1 are recycled.
Run `rlang::last_error()` to see where the error occurred.
in addition: Warning message:
Unknown or uninitialised column: `x1`.

what should I do?
