noWrap for addRasterImage

[jaseeverett]

For a global raster or SpatRaster, there seems to be no way to switch off wrapping when using leaflet::addRasterImage. It would be great if something similar to options = tileOptions(noWrap = TRUE) could be implemented for rasters as well.

Is there a workaround that I am missing?

library(leaflet)
library(raster)

r <- raster(xmn = -180, xmx = 180, ymn = -30, ymx = 30, nrows = 178, ncols = 360, crs = "EPSG:4326")
values(r) <- matrix(1:(178*360), nrow(r), ncol(r), byrow = FALSE)

pal <- leaflet::colorNumeric("Spectral", values(r),
                             na.color = "transparent")

leaflet::leaflet() %>%
  addTiles(options = leaflet::tileOptions(noWrap = TRUE)) %>%
  leaflet::addRasterImage(r, colors = pal) 

In this example, the map is not wrapped, but the raster layer is wrapped and I can't find a way to stop it happening.
Thanks for a great package. Any advice appreciated.
