Also... this: ``` > st_distance(lines, pt) [,1] [1,] 8.21824e-17 [2,] 0.00000e+00 ``` where I get some variation on `0` running many times with different random line end offsets, but the...

So this is obviously the 'feature-not-a-bug' that prevents me using `lwgeom::st_split` to successfully break linestrings at all their points of intersection. I've written code that works around it by inserting...

Thanks for the information. The irony is that since I am making the points by intersecting the lines, I already _know_ that they intersect them. As I noted in passing...

My (limited) understanding of GWR would be that all these scaling factors will cancel out since it's all relative anyway. This was just something I came across along the way...

My thought would be to offer a keyword argument either boolean or some string constant depending on how many options you want to support. One of the options should certainly...

```Yes @mdsumner I'm fully aware that not every crs has such a visible boundary (not even WGS84/Mercator)``` _Especially_ not Mercator! A `tmap` function that resolved this problem for even a...

I am in the habit when plotting geographical data (which is eventually the aim here) to include `asp = 1` in plot options as _usually_ you want geographic coordinates to...

The documentation could perhaps add something like > For directed graphs the normalization factor is changed to $2B^n$.

My mistake on the suggested edit - don't know what I was thinking! Unfortunately, I am a frequent user of many different FOSS packages but by no means an expert...

This is simple for tiling elements that are regular polygons. It's less straightforward for other shapes.
