Describe the bugrepeat_view = TRUE leads to a frozen view within Shiny with the browser console returning plenty of Uncaught TypeError: cyclic object value
To Reproduce
library(data.table)
library(sf)
library(mapdeck)
library(shiny)
key <- "***"
set_token(key)
n <- 1000L; x0 <- -179; y0 <- -42
pts <- data.table(x = rnorm(n, x0, 2), y = rnorm(n, y0, 2), indiv = sample(LETTERS, n, repl=T))
pts <- st_as_sf(pts, coords = c('x', 'y'), crs = 4326, remove = F)
shinyApp(
ui = fluidPage(mapdeckOutput('map', height='800px')),
server = function(input, output) {
output$map <-renderMapdeck({
mapdeck(location = c(x0, y0) , zoom = 3 ,
style = 'mapbox://styles/mapbox/dark-v10' , show_view_state = TRUE ,
repeat_view = TRUE) %>%
add_scatterplot(data = pts , fill_colour = "indiv" , fill_opacity = 0.5 ,
stroke_opacity = 0 , radius_min_pixels = 2 ,
palette = 'rainbow_hcl')
})
}
)
Expected behaviour
Features on both sides of the international date line should get displayed with repeat_view=TRUE. This option is essential when dealing with features around the date line, as otherwise half of them disappear when dragging the view left or right.
