%description
Functions that compute rational approximations of fractional elliptic
stochastic partial differential equations. The package also contains
functions for common statistical usage of these approximations. The main
references for rSPDE are Bolin, Simas and Xiong (2023)
<doi:10.1080/10618600.2023.2231051> for the covariance-based method and
Bolin and Kirchner (2020) <doi:10.1080/10618600.2019.1665537> for the
operator-based rational approximation. These can be generated by the
citation function in R.
