Dear Basile, the %>% operator is accidentally commented out! Change fillOpacity = 0.7)#%>% to fillOpacity = 0.7) %>% and then setView() will get its first parameter called "map".

Hello everyone! I am trying to create a shiny app with leaflet stuff in it. I have a problem when I am displaying the application, I got this error message : "Error in dispatch: argument "map" is missing, with no default". I searched some clues on the net, I found some examples which are working but I do not get where I going wrong. I double checked the brackets, try to change the name of the map, put the name of the spatial data frame that I am using, etc. If someone can give me some clues I will be really glad. Have a great day, thank you for your time, Basile. Here is my code: ui <- fluidPage( titlePanel(""), sidebarLayout( sidebarPanel( helpText(""), selectInput("var", label = "Choose a variable to display", choices = spdf$koppen, selected = "" ), sliderInput("range", "surface brûlée en hectare", min(spdf$V11), max(spdf$V11), value = range(df$V11), step = 2500 ), sliderInput("range", "Nombre d'incendie", min(spdf$n), max(spdf$n), value = range(df$V11), step = 2 ), checkboxInput("legend", "Show legend", TRUE)), mainPanel(leafletOutput("map")) ) ) server <- function(input, output, session) { output$map <- renderLeaflet({ leaflet(df) %>% addTiles(group = "OSM") %>% addProviderTiles("Esri.NatGeoWorldMap", group="ESRI") %>% addProviderTiles("CartoDB.DarkMatter", group= "CartoDB") %>% #fitBounds(~min(long), ~min(lat), ~max(long), ~max(lat))%>% addPolygons( data=spdf, fillColor = "viridis", weight = 0, opacity = 1, color = "white", dashArray = "3", fillOpacity = 0.7)#%>% setView(lat= 44.2, lng=5.9, zoom=5) }) } shinyApp(ui, server) Sent with [ProtonMail](https://protonmail.com) Secure Email.
