Slider values doesn't update on observeEvent when nested in tabPanel

Asked 2022-Jan-31 at 08:42

I am using a date slider that is dynamic on the selection of year from the UI. The slider options are nested in tabPanel but when the year is changed the date does not react. I don't understand how to get the observeEvent to relay the new date. The old date can be seen in the terminal from the discrepancy of print(input$range) vs print(input$year) when the year is changed to 2018. Any help is greatly appreciated!

In my opinion, I think the conflicts is due to both inputs having the same id "range". By giving them different id, it works for me.

I made the following changes :

give the sliderInputs different id, i.e "range1" and "range2" instead of "range".

QUESTION

hasOwnProperty() is only checking if a certain property exists in a JSON, but doesn't return anything if it doesn't

Asked 2022-Jan-15 at 01:05

I keep trying different methods to check if this JSON contains "attributes." In this way I can determine if the given coordinates are outside of wetlands. If they are in wetlands, "attributes" will exist in the JSON. If they aren't in wetlands, 'attributes' won't be in the JSON.

When I run this function, I am only getting TRUE - when I type in coordinates that are in a wetland (try 43.088 instead, in the JSON url, which returns true).

However I want FALSE for the given url. For some reason when I do console.log("FALSE"), this doesn't appear or return in the console at all if hasOwnProperty('attributes') == false.

Am I missing something?

ArcGis Rest API - How to get raster layer from MapServer?

Asked 2022-Jan-04 at 17:01

I am trying to get a raster layer (5-metre Digital Elevation Model (DEM)) from the Australian government through the ArcGIS REST API

url: https://services.ga.gov.au/site_9/rest/services/DEM_LiDAR_5m/MapServer/

I can perform a query for the boundary and footprint layers with good results

boundary query:

"https://services.ga.gov.au/site_9/rest/services/DEM_LiDAR_5m/MapServer/1/query?where=&text=&objectIds=&time=&geometry=xmin:133.226100657682, ymin:-23.6165145646468, xmax:133.235899342318, ymax:-23.6074854353532&geometryType=esriGeometryEnvelope&inSR=4283&spatialRel=esriSpatialRelEnvelopeIntersects&relationParam=&outFields=&returnGeometry=true&maxAllowableOffset=&geometryPrecision=&outSR=&returnIdsOnly=false&returnCountOnly=false&orderByFields=&groupByFieldsForStatistics=&outStatistics=&returnZ=false&returnM=false&gdbVersion=&returnDistinctValues=false&f=json"

response (plotted in R):

R plot through jsonlite response

Footprint query:

"https://services.ga.gov.au/site_9/rest/services/DEM_LiDAR_5m/MapServer/2/query?where=&text=&objectIds=&time=&geometry=xmin:133.226100657682, ymin:-23.6165145646468, xmax:133.235899342318, ymax:-23.6074854353532&geometryType=esriGeometryEnvelope&inSR=4283&spatialRel=esriSpatialRelEnvelopeIntersects&relationParam=&outFields=&returnGeometry=true&maxAllowableOffset=&geometryPrecision=&outSR=&returnIdsOnly=false&returnCountOnly=false&orderByFields=&groupByFieldsForStatistics=&outStatistics=&returnZ=false&returnM=false&gdbVersion=&returnDistinctValues=false&f=json"

response:

jsonlite response in R

where I got the name of TIF files I am looking for, nevertheless all my queryes to the raster layer: https://services.ga.gov.au/site_9/rest/services/DEM_LiDAR_5m/MapServer/3 does not give me any result

I have tried the rcran package "arcpullr" as well, but no results

any help?

ANSWER

Answered 2022-Jan-04 at 17:01

So most likely data provider has disabled the query operation on the 3rd layer of that map service. Also, no fields are enabled on the layer 3, so there is nothing to query or return through a query operation.

So only export operation would work on that by providing a bbox (which you can use also by using the results of the footprint layer).

Show and hide text in modularized shiny app based on actionButton() and shinyJS()

Asked 2022-Jan-03 at 18:57

In the modularized shiny app below Im trying to display a message when the app is loaded for first time and then when I click the actionButton() this message is being hidden using shinyJs() and the plots are displayed. But the message is not displayed from the beginning.

ANSWER

Answered 2022-Jan-03 at 18:57

Three things are wrong:

you use renderUI() but you have verbatimTextOutput in the UI part. You need to use uiOutput() instead
you forgot to call textUI("textPL") in the UI part
you want to hide the text when input$action is clicked, but this input is defined in another module. Therefore it has a different namespace and clicking it doesn't trigger hide(). You need to pass the "click" through modules. There's a similar post about that here.

Next time, you should also provide a minimal example, there is a lot of code that is irrelevant to the problem here.

Here's the working code:

Display two visualizations that are based on two different dataframes in modularized shiny app

Asked 2022-Jan-03 at 13:19

In the modularized shiny app below I want to create one map which is created and one plot below the map. The 2 visualizations are based on 2 different dataframes though and I do not know exactly how display them both.

...

ANSWER

Answered 2022-Jan-03 at 13:19

You have plotlyOutput(ns("plot")) in different module than server where is output$plot<-renderPlotly({ (the latter is in plotServer while ui output is in mapUI). I decided to make new ui for plotServer, but you can also try to move elements from plotServer into mapServer.
As you said, the problem is with returning multiple elements. But not just two dataframes, also some input. To return more than one element, you need to create list, say like this: return(list(element1 = _object_to_return1, element2 = _object_to_return2)).
I said above "return some input", that's because here: fig%>% layout(title = paste("Count of",input$sci ,"through the years") you are using input, but input from different module. As you already know, you do not have direct access to objects from different modules and the same is with inputs. That means you need to return input as well, but input needs to be wrapped into reactive() function. In your case, when there is module with two returns function, it should be one and look like this: return(list(react = react, counted = counted, sci = reactive(input$sci))) .
Now, because you have returned list, you need to access elements inside this list as normal elements from list, so when you pass arguments to function, it won't be react as previously, but city_input$react. You also need to add parameters to the server function - not just city, but also parameter for counted dataframe and input.
In case it won't be obvious for you - to access input from other module (after passing as argument) you access it as a normal function, so below you can see that I use sci() instead of input$sci

Leaflet: Change color onClick

Asked 2021-Nov-06 at 15:50

I am trying to change the color of my GeoJSON-Layer on every click in my Ionic React App, but I only managed to change it once for the first click... My idea was to change the color between blue and red everytime a feature is clicked. I had the idea to check for the color in the options of the GeoJSON-Layer, but as written, it only changes the color once for the first click and afterwards nothing happens on any other click.

...

ANSWER

Answered 2021-Nov-06 at 15:50

There is a really much simpler way to achieve the desired behavior. I can give an example using one geojson and then you can adjust it to your needs.

You need to reset geojson style after each layer click. You can achieve that by taking a geojson reference using react ref and leaflet's resetStyle method. And regarding the change of the style you only need to set the color after each click. No need for if statements there.
