gg_df.rspde_result

Returns a ggplot-friendly data-frame with the marginal posterior densities.

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.

gg_df.rspde_result function

<dl><dt>result</dt>
<dd>An rspde_result object.</dd>
<dt>parameter</dt>
<dd>Vector. Which parameters to get the posterior density in the data.frame? The options are <code>std.dev</code>, <code>range</code>, <code>tau</code>, <code>kappa</code> and <code>nu</code>.</dd>
<dt>transform</dt>
<dd>Should the posterior density be given in the original scale?</dd>
<dt>restrict_x_axis</dt>
<dd>Variables to restrict the range of x axis based on quantiles.</dd>
<dt>restrict_quantiles</dt>
<dd>Named list of quantiles to restrict x axis. It should contain the name of the parameter
along with a vector with two elements specifying the lower and upper quantiles. The names should be
match the ones in result$params. For example, if we want to restrict nu to the 0.05 and 0.95 quantiles
we do <code>restrict_quantiles = c(0.05, 0.95)</code>.</dd>
