Error in fmesher.read(prefix, "manifold") :

[Ania Kawiecki]

Hi! I'm getting a very strange error now when I try to make a mesh in INLA. 

This is what happened: I updated to R 4.1.0, realized INLA didn't work on there. So I went back to "R version 3.6.3 (2020-02-29)", re-installed INLA and then this error started happening (see below). 

Am on macOS Big Sur Version 11.2.3. 

Any help would be much appreciated!!!  Thanks!

try to install R-4.0 instead of the R-3.6. I guess you're on the Intel
and not the M1, right ? If you're on the M1, you'll need to to install
R-4.1 and download the M1 build of INLA

sure you do not want to call inla.mesh.1d() ?

Where can you find the M1 build of INLA?

[Helpdesk (Haavard Rue)]

If you install, as described at r-inla.org, then it should pick it up
automatically.

otherwise, you can always download it manually from inla.r-inla-
download.org
