The problem is that line_width_units
defaults to "meters"
, so your lines 1m wide. This a bad default in my opinion.
Try this
library(rdeck)
library(dplyr)
library(sf)
library(absmapsdata)
shp <- sa32016 %>%
filter(gcc_name_2016 == "Greater Melbourne")
rdeck(
map_style = mapbox_dark(),
# set the bounds of the map to include all of the manhattan data
initial_bounds = st_bbox(shp),
# add a 2 pixel buffer to each point, making it easier to hover
picking_radius = 2
) |>
add_polygon_layer(
data = shp,
get_polygon = geometry,
filled = TRUE,
opacity = 0.1,
stroked = TRUE,
get_line_color = "#663399ff",
line_width_units = "pixels",
)

Interesting, when I run that script I don't get any outlines at all:

I also have a broken display in the RStudio Viewer, so I'm looking in the webpage. Not sure if that's connected or not, or perhaps it is an R version issue?
Oh never mind, this is solved with a line_width_min_pixels
argument, so I guess it is related to a default zoom level or something like that.
I'll consider this one closed.
The above (https://github.com/qfes/rdeck/issues/91#issuecomment-1447564187) should have just worked as is, because the default get_line_width = 1
. line_width_min_pixels = 1
also works in this case, since you'll (likely) not get > 1 pixel for 1m lines.

If you're using a QtWebEngine version RStudio, rdeck probably won't render in the viewer. I removed legacy browser support (QtWebEngine-RStudio viewer was locked to Chrome 69) from rdeck in v0.5.1.
Rdeck renders in the Electron-RStudio viewer. I've just run the above script on the latest RStudio release for windows:
I'm trying to add a flat polygon layer, with a stroke on the outside. I can get a thin line by setting
stroked = TRUE
andextruded=TRUE
, but I haven't managed to get a thick line, and the outline isn't really visible enough.I have tried setting
get_line_width
to a large number, but it seems to have no effect.Here is a short example showing the unexpected behaviour
