update.CBrSPDEobj2d {rSPDE} | R Documentation |
Update parameters of CBrSPDEobj2d objects
Description
Function to change the parameters of a CBrSPDEobj object
Usage
## S3 method for class 'CBrSPDEobj2d'
update(
object,
hx = NULL,
hy = NULL,
hxy = NULL,
sigma = NULL,
nu = NULL,
m = NULL,
...
)
Arguments
object |
The covariance-based rational SPDE approximation,
computed using |
hx |
If non-null, update the hx parameter. |
hy |
If non-null, update the hy parameter. |
hxy |
If non-null, update the hxy parameter. |
sigma |
If non-null, update the standard deviation of the covariance function. |
nu |
If non-null, update the shape parameter of the covariance function. Will be used if parameterization is 'matern'. |
m |
If non-null, update the order of the rational approximation, which needs to be a positive integer. |
... |
Currently not used. |
Value
It returns an object of class "CBrSPDEobj2d.
