            How do you exclude NA values from Leaflet legend?
            Asked 2021-Jun-04 at 17:56

            Here's my data:

            Updated data output from dput: redacted

            I'm trying to replicate the following plot:

            Here's the code I've used to replicate so far, the only thing I can't figure out is how to remove the NA from the legend.



            Answered 2021-Mar-17 at 04:31

            The function addLegend() has an argument na.label which by default is set to "NA". From here it seems one can set na.label = "" to remove the NA label from the legend.



            Plotting longitude and latitude on a map and create line for each subset (every row in DataFarame)
            Asked 2021-Apr-06 at 12:19

            I worked a lot on my data set to make it like following. I know how to plot each latitude and longitude in folium as below. I have no idea how to plot line (Polygone) between each pairs of latitude and longitude of my data set in each row. As we see each row is combination of latitude and longitude.

            The code is for showing each point( lat and long) on the map.

            Notice: I didn't write this code for the provided DataFrame. it is for a data frame with a column named "start_station_latitude" and other column start_station_longitude.



            Answered 2021-Apr-06 at 12:19

            I'm not sure I understood your question perfectly. How I understand it, you have a df with three latitudes and three longitudes on every row and you want to draw a line throug these three points. If that is what you mean, you could try this:



            Removing markers and clear sources not working. The markers remain on the map
            Asked 2021-Apr-04 at 06:46

            I inherited this code of an openlayers map, but I am not able to remove all markers to reset the map and redraw.
            I added the resetMap function at the end of the file:



            Answered 2021-Apr-04 at 05:34

            I solved.
            The problem was I was adding new layer of markers without deleting old one.

            This is the new version of addCluster function, where first of all I name the cluster, and I remove it (if exists) before adding new one:



            How to trigger action on clicking in menuItem?
            Asked 2021-Apr-03 at 16:17

            I want to trigger some action on clicking the menuItem. I use observe here: when I click 'Drivers' item I want some text to be returned in the console. Unfortunately, when I run the app the error comes up: Error in if: argument is of length 0. My menuItem exists, id is also ok so don't know why this error shows up. Here is reproducible code (observe is on the bottom of my code):

            Leaflet in R: automatically setting view according to one layer
            Asked 2021-Mar-27 at 11:29

            I am making some maps in Leaflet in R, and the maps consist of a polygon layer as well as a layer of markers. The polygon usually covers a larger area than the markers, but I want to zoom specifically to the marker area.

            I know I can manually specify lat/longs and zoom level, but I don't want to do that because this code will generate a lot of different maps covering different subsets of my dataset (or on different datasets).

            Here's a simplified version of the code that generates the map. I don't think this necessarily requires a full reprex to answer the question but can do so if necessary.

            Have you tried fitBounds? Starting from what you have posted, I would first get the bbox coordinates of your markers:

            How to build dynamic Leaflet Map in RShiny?
            Asked 2021-Mar-21 at 13:48

            I am a beginner in Shiny and trying to build a shiny app where a user can select State location from drop down and then based on those the lat & long should be plotted on the leaflet map.

            I have looked at several SO post like Shiny dropdown menu selection to filter a dataframe and shiny tutorials but nothing has completely worked to make it dynamic based on dropdown selection.

            I have also tried using reactive() in my latest code attempt which I have posted below.

            Error: addCircleMarkers requires non-NULL longitude/latitude values

            Where am i suppose to put the data to not get this error?

            I have also checked other SO post like: addMarkers requires non-NULL longitude/latitude values in R Shiny

            But still not sure what exactly is wrong here.



            Answered 2021-Mar-21 at 08:03

            The column names are called Longitude* and Latitude* and in ui you have to use leafletOutput instead of plotOutput.

            How do I clear the markers on a leaflet map linked with a DT?
            Asked 2021-Feb-04 at 10:33

            Based on this example it is possible to link DT and leaflet. Selected rows on DT are ploted on leaflet. I've made some modifications to be able to have a map by default ~markers ploted in red, then when the user select a row on DT, the marker on leaflet is highligted in blue.It works fine so far. 1- However, when the row is unselected on the DT the blue highlight still shows. How to solve this problem. 2 - Using the action button ~ Clear table selections ~ remove all the markers blues and reds. However, I just would like to make the blue highlight disapear still keeping my red markers.

            my code below with reproducible example. Thank you

            This solution here works as intended and gets rid of a lot of unnecessary reactives/observer:
