I am trying to fit Polish local government election results in 2015 following the superb blog by @GavinSimpson. https://www.fromthebottomoftheheap.net/2017/10/19/first-steps-with-mrf-smooths/ I joi...

I would like to create a map showing local spatial cluster of a phenomenon, preferably using Local Moran (LISA). In the reproducible example below, I calculate the local moran's index using spdep ...

I would like to create a map showing the bi-variate spatial correlation between two variables. This could be done either by doing a LISA map of bivariate Moran's I spatial correlation or using the ...

I have a panel dataset with several hundred regions, ~10 years and spatial data for the regions. I created a weight matrix with the spdeppackage (via the standard way, and then, nb2listw). I have,...

I want to cluster the codebook from a self-organizing map using k-means clustering. However, given the 'spatial' nature of the data, I want to constrain the clustering so that only contiguous nodes...

I have 4000 records of volume in trees plantation. I need to calculate the Moran's I to the whole plantation. I use ape library because spdep is said to be slower. My code is this: # Modified from...
