adding a bravais pearson test to spplot

Well, creating an example from scratch to show you how it is done can be a lot of work, and depending on your specific data such code can end up being wasted work. For this reason the polite thing to do is to provide a minimal reproducible example that list readers can use to start from. [1]

Also, you should read the Posting Guide, which warns you that the R mailing lists are plain text only, so if you post HTML as you did then at best we don't see what you see and at worst it is corrupted. The Guide also mentions that there are different lists with different topics, and the topic of your question is probably best addressed on the R-sig-geo mailing list. It looks nontrivial to me, but there might be a canned solution out there.

Dear all,
My name is Bilel and I'am a PhD student from Tunisia working on climate
modelling. My issue today is how to add a Bravais Pearson test as a
contour plot to an existing spplot map. Precisely, I have plotted a
SpatialPixelsDataFrame of Pearson correlation coefficients between
simulated and observed precipitation over the Mediterranean basin using
spplot and I need to now add a contour line of the statically
significant correlation coefficient at 95% CI.I have been vainly trying
for several days to solve this issue, so I really need your help please
Best regards?Bilel?
