I'm trying to create a dashboard linked with an SQL database with renderValueBox function, but I'm not able to filter between dates.

The problem: Including an emoticon to a parent/child table mutes the child table. How to overcome this difficulty?

The added issue is that the inclusion of virtually any special character leads to the same result. I suspect that the answer is in the call back but it beats my JS skills.

The code:

I am trying to fix my width on my R Shiny map. Also, I am not succeeding in making the panel faded. The width and faded panel I want to replicate is here at this link:

I am using their style css file, this link: https://github.com/rstudio/shiny-examples/blob/master/063-superzip-example/styles.css

I have written my code:

I'm trying to change the shinyApp here, so I have added two inputs to choose from when you want to graph the data. One column of my data is a date. I wasn't able to graph the data. I tried to factor the date field, but it might be the problem with the ShinyApp variables types because I tried to graph the data on a seperate example and it worked. I noticed the original example is using paste to format the input$x that is sent by the UI to the server, using function regFormula (). I tried to change the structure, and even get rid of it. Still having error. Also, I tried to use zoo package which works again on a seperate example not inside the app.

here is the dataframe-using dput:

I am attempting to create a Dockerized Flexdashboard app. I am able to run it locally, but not in the localhost. I can, however, run shiny apps just fine within the same docker image. Interestingly, the error message in the localhost says 'Not Found' for the Flexdashboard app which is different than when a page doesn't exist at all ('Page Not Found').

How can I Dockerize a Flexdashboard app?
