comment What are the benefits of hexagonal sampling polygons?
Why is having six adjacent neighbors a drawback? Six neighbors allows for less computation. Additionally, these six neighbors all have the same distance to the hex center. Square grids may have 2 definitions with regards to neighbors. 4 neighbors that share an edge, 8 neighbors, share an edge and vertex. With a square grid, only 4 neighbors that share a edge have the same distance to the grid center, while the other 4 that share a vertex have different (longer) distance to grid center.

revised Does the USDA SSURGO database have a web-based API that I can query?
I corrected the govt agency that hosts SSURGO data. The USDA, not the USGS.

Also, a post should only contain 1 question, not two.

This sounds like you need help with a HW problem. Check out the SPGWR package cran.r-project.org/web/packages/spgwr/vignettes/GWR.pdf
