Error running "inlasloo"

[jcavieresg]

Hi everyone!

I'm trying to run loo-cv for a spatial model using simulated data. I have been following the example from the INLAutils package (https://github.com/timcdlucas/INLAutils?tab=readme-ov-file#spatial-leave-one-out-cross-validation-sloo-cv) but I'm having this error:

\textttt{Error in if (class(mesh) != "inla.mesh") stop("unexpected class instead of inla.mesh class for the argument "mesh"") :
the condition has length > 1}

I would be grateful if you can help me!
Thanks,

I wouldn't be surprised if this is because INLA has pulled lots of code out into fmesher. I'll try to have a look but might require quite an extensive rewrite of inlautils so it might not be quick.

Hi Tim

Yes, looking at class of the mesh created in my computer, it seems that it comes from the library "fmesher":

class(mesh)
[1] "fm_mesh_2d" "inla.mesh"

fm_mesh_2d object:
Manifold: R2
V / E / T: 37 / 87 / 51
Euler char.: 1
Constraints: 21 boundary edges (1 group: 0), 12 interior edges (1 group: 0)
Bounding box: (-3.777535, 6.812768) x (-3.589064, 2.869430) x (0,0)
Basis d.o.f.: 37

But also it is a inla.mesh object, so something could be there to help you (maybe?)...
Thanks for your help!

Best,

Ah, I might just be able to switch class(mesh) != "inla.mesh" to inherits("inla.mesh"). The earlier version is bad coding anyway!
