SPDE Simulation

Postby mharley » Mon Sep 04, 2017 3:13 pm

I tried to run an unconditional simulation via the SPDE Simulation methodology. I followed exactly the steps shown in the SPDE first-steps vignette. However as soon as the SPDE process initiates, the R-session crashes.

Please, could you provide us more information?
- The vignette step when the crash occurs
- The version or RGeostats
- Your operating system...
Please follow these instructions:

Hello Fabien,
I am following the vignette by copying and pasting the results into my RStudio Console
The command that causes R to terminate is this:
result.nc = spde(,grid,model,seed=seed,gext=gext,nbsimu=nbsimu)

The output requested is:
> library(RGeostats)
Loading required package: Rcpp
Loading RGeostats - Version:11.1.0

Sorry for my late answer,
Did you tried with the last version or RGeostats ?

Bonjour,

J'ai subi le même crash systématique. J'utilise la version 11.2.0 sous Windows 8.1.
Le crash se produit à la ligne 266 :
result.nc = spde(,grid,model,seed=seed,gext=gext,nbsimu=nbsimu)

Merci de proposer une solution,

Dimitri

Dear,

Sorry for our late answer.
We have fixed the spde function in the last release of RGeostats under Windows (11.2.1).
Hope this helps !

Best regards,
Fabien

Dear Fabian,

I tested again on version 11.2.1 under Windows 8.1 and I still have the same crash...
Any guess of what is happening?

Thank you,
Dimitri

Fabien,

Thank you for the new version. It solves the problem.

I just had a "unused parameters numparts=c(4,4),npiter=10" causing an error at line 530. I removed them and reached the end of the Rmd file.

I presume those parameters are obsolete, right?

Thank you,

Dimitri

Hi Dimitri
You are right, the parameters numparts was refering to the quilting option which has been abandoned.
I am even surprised that you could still see any reference to this parameter: I did not find any in the today's distribution.
But SPDE is constantly evolving ... so some obsolete parameters may remain ... by mistake.
