support for sf objects

[dominicroye]

I have tried to use geom_glowpath() with a simple feature line, but it's always giving the grouping error of only one observation when I include stat = "sf_coordinates". It works fine with points.

library(sf)
library(ggshadow)
library(tidyverse)

# point glow with sf
point <- st_point(c(4.351667, 50.846667)) |> 
                st_sfc(crs = 4326) |>
                 st_transform(3035)

ggplot(point, aes(geometry = geometry)) + geom_glowpoint(stat = "sf_coordinates", size = 5)  

# line 
pointbdf <- st_buffer(point, units::as_units(2500, "km")) |> 
                        st_as_sf() |> 
                          st_cast("LINESTRING") 
                 
ggplot(pointbdf, aes(geometry = x)) + geom_glowpath(stat = "sf_coordinates") 
geom_glowpath: Each group consists of only one observation. Do you need to adjust the group aesthetic?

Hi Dominic, There is nothing in the package itself that deals with sf objects, and I am unfamiliar with sf objects, so not sure if this has an easy fix. Does it work if your data contains two points instead of one?
