kandi X-RAY | leaflet.providers Summary

leaflet.providers is a R library typically used in Data Preparation applications. leaflet.providers has no bugs, it has no vulnerabilities and it has low support. However leaflet.providers has a Non-SPDX License. You can download it from GitHub.

The goal of leaflet.providers is to provide regularly updated data on the third-party tile providers supported by leaflet. The data is extracted from leaflet-providers.js. While leaflet.providers will be regularly released with updated providers data, the package comes with functions use_providers() and get_providers(), which enable users to fetch up-to-date providers information directly from leaflet-providers.js between package updates and to load this providers data in leaflet. Users may also fetch older versions of the providers data with the leaflet-providers.js version number.

Dynamic reactive objects conflits with observe combined with if

Asked 2021-Jun-05 at 23:04

I try to create an app in Shiny and all selectInput were dynamic reactive objects but at the moment they make some plot (output$myplot) with the combination of the variables select and if(){} condition using observe({}), my plot doesn't work (PEST == unique(stands_ds$PEST) : length of larger object is not multiple of length of smaller object). The problem is with the final selection object selectedvariable4 and try to used selectedvariable4, selectedvariable4(),selectedvariable4()$ID_UNIQUE and unique(selectedvariable4()$ID_UNIQUE) without success.

The lines where we are filtering and subset would have == and some of them on the rhs of the operator is unique values i.e. it could be a single value or more than one value. With ==, it is elementwise comparison and it can work only when the rhs object is of length 1 or have the same length as the lhs object. With length 1, it recycles and have no issue, but if the length is more than 1 and not equal to the other object, the recycling will do erroneous output and it may also gives the length warning if the length is not a multiple of the other object.

It may be safer to use %in% instead. Below is the updated code (not tested though)

The error mentioned in the OP's post is due to applying as.Date directly without any specificiation of format. By default, the format it uses is %Y-%m-%d i.e. YYYY-MM-DD. If the input format is anything else, it throws the error as below

ANSWER

Answered 2021-Jun-02 at 22:10

We can wrap the if-else statements in observe(). The reason reactive() is not called is because we are actually interested in the side effects here (eg declaring output$myplot. Also, a reactive (observe, reactive, eventReactive observeEvent) context is recommended whenever an input$.. is called because it's intended to change upon user's input.

Shiny ConditionalPanel fails to open on setInputValue update

Asked 2020-Oct-02 at 23:28

I'm learning how to use Shiny and ran into a problem.

I'm trying to make a ConditionalPanel open based on calling Shiny.setInputValue('myEvent', 'open', {priority: 'event'});

However, the panel doesn't open. I checked that the javascript event is being fired, so it seems like:

setInputValue is not occurring,
the UI is not receiving the event,
or, the event name isn't matching

I suspect it has something to do with reactivity, but I'm stuck. Code is below:

This seems to be an issue of some combinations of RStudio, R and leaflet versions on Windows, see these GitHub issues:

Viewer Pane not working for RStudio
Leaflet maps don't appear in RStudio Viewer Pane (Windows + R v4.0) for leaflet

Try to upgrade your RStudio, maybe it'll help (at least they say it's fixed for RStudio v1.3.957-1).

ANSWER

Answered 2020-May-15 at 19:24

The following code gives the expected output, your expected output is a list of vectors but input$map_click gives a list, a named list to be exact. To convert it to a vector, we used unlist, since your desired output doesn't have names in the vector as well, we used unname to remove the names. Also, if your code is breaking on app initialization due to the unavailability of some input, use req to have observers wait for that input. This is one of the recommended approaches to handle this kind of behavior. << is not recommended in shiny apps and is to be used very carefully. In your code, it was actually redundant.

leaflet searchbox returns no result

Asked 2020-Feb-04 at 19:27

I cannot get the sample data from a leaflet searchbox to work. I get no errors, but the 'timer' in the searchbox keeps spinning, and no results are returned.

The output-map on the website with the sample data, is working for me: https://rpubs.com/bhaskarvk/leaflet-search
However, when I run the code local, in Rstudio-viewer of in firefox, the searchbox is not working.

described solution below worked for me:

I figured out how to make the search work with the CircleMarkers (removing the path check), you have to go into your R library path : R Library path#\leaflet.extras\htmlwidgets\build\lfx-search\

Open lfx-search-prod.js and search for "e instanceof t.Path ||" , and then delete it and save the file. Your CircleMarker search should work now
