Spatial Dependence: Weighting Schemes and Statistics
Thanks for developing this package, I'm using this package to process spatial transcriptome data. I want to calculate the autocorrelation using `geary.test` function. But I found the code introduces a...
I am trying to find out the best way to identify the disconnected subgraphs from a `nb` object. In trying to explore how to convert an `nb` object to an...
Dear all, I created this issue since I have a (possibly trivial) question regarding the relationship between [`sgbp`](https://r-spatial.org/book/07-Introsf.html#binary-predicates) and [`nb`](https://r-spatial.org/book/14-Areal.html#representing-proximity-in-spdep) objects. According to the descriptions in the SDSR book, it...
@rsbivand, is it possible to set grouping criteria per group using `spdep::skater()`? So, suppose I want to cluster geometries into 3 groups such that the groups have the following population:...
`localG_perm()` lists three different p-values and it's not entirely clear which are which. My understanding is the following: - Pr(z != E(Gi)): "standard" p-value under the assumption of normality -...
I chatted briefly with @edzer at rstudio::conf and he mentioned the idea of writing tests and doing code coverage for spdep. Would this be something we'd be interested in? I...
Would it be possible to add a code of conduct to this Github repo? I think it's a good practice and encourages folks to feel comfortable submitting pull requests and...
Per suggestion in #162, I want to provide conversion functions to a `listw` object from ArcGIS spatial weights matrix representations. At the moment, I have prototyped a function for us...
@JosiahParry Could you take a look at this attempt to add 10mm as the default snap for projected `sf` object input and `1e-7` for geographical (`(180*0.01)/(pi*6378137)` is `8.983153e-08`, `(1e-7*pi*6378137)/180` is...
