geom_labelsf() not recognizing aesthetics about geomtextpath HOT 5 OPEN

Hi there,

Thanks for reporting the issue, I can confirm that this isn't currently handled as you'd expect. I'd know how to activate the text parameters, but I'm not sure how I'd go about the fill aesthetic, since it is ambiguous whether it should apply to the label or the fill of potential polygons in the geometry. @AllanCameron, you probably have a better idea how this works than I do, should we make a box_fill aesthetic that defaults to the fill aesthetic?

from geomtextpath.

The aesthetics work a bit differently within the sf geoms, and as Teun says, the fill aesthetic is already used. Instead, I used a boxfill aesthetic for geom_labelsf, which probably isn't documented very well. Having text_only is also ambiguous when you have collections of linestrings and polygons - what exactly would you leave out the plot?

However, it is possible to achieve what you want using the current version without much trouble:

library(tidyverse)
library(sf)
#> Linking to GEOS 3.9.1, GDAL 3.2.1, PROJ 7.2.1; sf_use_s2() is TRUE
library(geomtextpath)

sample_coords <- tibble(
  x = c(43.00778, 42.99675),
  y = c(-87.94263, -87.90710)
) %>%
  st_as_sf(coords = c("y", "x"), crs = 4326) %>%
  summarise() %>%
  st_cast(., "LINESTRING")

sample_coords %>%
  ggplot() +
  geom_labelsf(label = "Label", boxfill = "red",
               linewidth = 0)

Ah, got it. I only included the text_only piece as an example, but the real thing I was trying to do was fill the label. So, the boxfill option solves it for me. Thanks for the prompt attention here!

I'll leave this open until I get round to improving the docs for this feature. Thanks for raising it @Pecners

Excellent foresight, Allan!
