ptools feature engineering vignette update

For another update to my ptools R package in progress, I have added a vignette to go over the spatial feature engineering functions I have organized. These include creating vector spatial features (grid cells, hexagons, or Voronoi polygons), as well as RTM style features on the right hand side (e.g. distance to nearest, kernel density estimates at those polygon centroids, different weighted functions ala egohoods, etc.)

If you do install the package turning vignettes on you can see it:

install_github("apwheele/ptools", build_vignettes = TRUE)

Here is an example of hexgrids over NYC (I have datasets for NYC Shootings, NYC boroughs, NYC Outdoor Cafes, and NYC liquor licenses to illustrate the functions).

The individual functions I think are reasonably documented, but it is somewhat annoying to get an overview of them all. If you go to something like “?Documents/R/win-library/4.1/ptools/html/00Index.html” (or wherever your package installation folder is) you can see all of the functions currently in the package in one place (is there a nice way to pull this up using help()?). But between this vignette and the Readme on the front github page you get a pretty good overview of the current package functionality.

I am still flip flopping whether to bother to submit to CRAN. Installing from github is so easy not sure it is worth the hassle while I continually add in new things to the package. And I foresee tinkering with it for an extended period of time.

Always feel free to contribute, I want to not only add more functions, but should continue to do unit tests and add in more vignettes.
