I have the shiny app below in which I subset based on the selectInput() and then create a bar plot like in the image attached but for some reasons what I get is an empty plot.

I created a website with several pages using R markdown.The first page just contains introductory text. The second page consists of four tabs, each for a shiny app (map or table).

Has anyone come across a solution that would take a list of named items and generate a corresponding set of shiny input fields… With checkboxes where the input class is logical, etc.

The app basically get the uploaded file and saves it on the www/img folder.

I am working on a project that will allow the user to specify certain inputs and then generate some tables and plots. The user selects some options and various outputs are generated. I want to allow the user to modify the inputs and then easily compare the outputs from the various ‘runs’.

I want to refer to a specific element of a vector input in a conditional panel. For instance, suppose the user gets a checkbox group input with two fruit options- Apple and Banana. If the user selects only Apple and not Banana, a conditional panel is created that further prompts the user to select the color of the Apple (Red or green). If the user instead selects only Banana, a separate conditional panel is created that asks for the color of the Banana (green or yellow). I tried doing this with input.fruit.includes() as a condition, but this fails. Is there any other way to do this in R shiny? More generally, how do I put in a condition that asks for a specific element to be contained in a vector. Thanks!

I was trying to get a sense for how checkbox group input values can be stored in R shiny. I want to condition on them on the server side. Let’s say my goal is the following- the user gets to check one to three fruits (Apple, Orange, Banana). Subsequently, based on the input, the app prints outputs. If ‘Apple’ is included in the input, it prints ‘Apples are great!’. Otherwise it prints ‘Please include an apple daily’.

I’ve come across what seems to be some sort of anomaly, whereby on the homepage when I input content it pushes the end of the page beyond the footer in equal measure to how much content has been entered.

I have the following shiny app. When I select a metric in the ui, it switches for a second and then resets.
