Dear all,
I'd like to use the OpenCycleMap as background image in a leaflet map.
This requires an API key. I've stored the key in an environment
variable. Below is a minimal example of the leaflet map. I still get
the "API Key Required" message on the tiles. Any suggestions?
library(leaflet)
leaflet() %>%
addProviderTiles(
"Thunderforest.OpenCycleMap",
options = providerTileOptions(apikey = Sys.getenv("OCM_API"))
)
Best regards,
