%description
Contain code to work with a C struct, in short cgeneric, to define a
Gaussian Markov random (GMRF) model. The cgeneric contain code to specify
GMRF elements such as the graph and the precision matrix, and also the
initial and prior for its parameters, useful for model inference. It can
be accessed from a C program and is the recommended way to implement new
GMRF models in the 'INLA' package (<https://www.r-inla.org>). The
'INLAtools' implement functions to evaluate each one of the model
specifications from R. The implemented functionalities leverage the use of
'cgeneric' models and provide a way to debug the code as well to work with
the prior for the model parameters and to sample from it. A very useful
functionality is the Kronecker product method that creates a new model
from multiple cgeneric models. It also works with the rgeneric, the R
version of the cgeneric intended to easy try implementation of new GMRF
models. The Kronecker between two cgeneric models was used in Sterrantino
et. al. (2024) <doi:10.1007/s10260-025-00788-y>, and can be used to build
the spatio-temporal intrinsic interaction models for what the needed
constraints are automatically set.
