Techinically, the package is installed in an R library. You are using 
Rstudio as your IDE, but it does not run packages.

Despite setting dep=TRUE is still got a warning:

"Warning in install.packages :
   dependencies ‘Ecdat’, ‘mpoly’, ‘symmoments’ are not available"

Despite the warning, INLA installed and loaded without complaint and the 
code ran without error.

I later ran:

install.packages(c('Ecdat', 'mpoly', 'symmoments'))        # no problems 
here either.

So I'm unable to recreate your error.



R version 4.0.4 (2021-02-15)       #I'm admittedly not up-to-date, If 
you are,  then provide details

I did check to see if there are any later versions of pkg:INLA and could 
not find any
