clearcontrol | ClearControl - Real-Time and High-Performance Control | Microservice library

I'm exporting a leaflet map from a Shiny app. Everything works fine, until I want to add a legend for my colour-coded points (based on a variable). The colour-coding works fine, and adding the usual legend with leafletProxy works fine, but to have the export working, I need to use a custom-defined function to create the map, and that seems to break when I use my usual addLegend for the colour palette.

Any advice would be appreciated!

I have an app with a map that is being downloaded. I'm stumped as to why the spatial extent / zoom of the downloaded image is so different from what is being displayed on the screen. Looking for any suggestions to make the output match as close as possible the map displayed in the app itself...

I am creating an app with shiny + leaflet. When I launch the shiny app for the very first time, I try to show all the default values of the layers displayed by addLayersControl. Is there a way to specify show / hide?

For example, if you have the following code. (See R leaflet - Show/Hide addControl() element with group layers)

I implemented code in Java to retrieve data from the Firebase database by searching with an ID and show it in the form. If I add the id it will show the data correctly.

Successfully retrieved data

Data in firebase

But when I try to delete or update this data it is always showing as "No data resource". I tried to implement code but it is not working. How can I delete and update a specific data( Searched by ID),

The whole code I have tried..

I'm building an interactive map with Shiny and I'm currently trying to hide my UI elements in a dropdownButton from the shinyWidgets pkg.

My problem is that so far I can either have the dropdownButton working and having to remove the width = "100%", height = "100%" from my leafletOutput

OR

having my map as I want it and the dropdownButton being invisible.

Is there a way of having both? Thanks!

Here's a reprex:

I'm trying to make a horizontal legend in a Shiny app with a Leaflet map.

I can change the display to display: flex; using CSS which makes the legend horizontal but what I'm aiming at is something like:

0% - a palette of colors - 100%

edit and NOT -color- 0% -color- 10% - color- 20% etc.

I don't see a way to do that in CSS and I can't find enough info about addLegend to find a solution,

Here's a reprex:

I am using the leaflet function to create an interactive map within the shiny framework. Everything looks great except the legend. The colors of the legend are somewhat faded and therefore not perfectly represent the colors of polygons. How can this be solved?

I have used code based on this example from :https://www.r-graph-gallery.com/4-tricks-for-working-with-r-leaflet-and-shiny/

I would like my map to start out with none of the circle markers added and then to have them added or removed as the user interacts with the available options.

This is how it currently looks when a user loads the map:

And this is how I would like it to look when a user loads the map:

I've tried removing groups and layers and nothing seems to work. I am very likely missing something quite obvious. Thanks :)

I am building an app based on election results and I would like to colour the polygons on the leaflet map with the elected parties' colours per electorate. The user can select the year for which the choose to see the results: Sitting Party (current), 2013 etc.

I have read a lot on here about dynamic colour palettes and reactive colour palettes based on user input but none of them work with my pre-defined colour palette which sets a specific colour to each party abbreviation based on the party colours.

I am not sure what I am missing or doing wrong, but help will be greatly appreciated.

You can download the shp files here here, I used the Queensland 2018 distributions: https://www.aec.gov.au/electorates/gis/

And here is the elected party data which I merged with the shape file on the field Elect_div:
