dashboardthemes | custom theme support for R Shinydashboard applications | Theme library

Try as.numeric(input$FDR) in your filter as shown below.

Using mtcars as example this works for me to get a horizontal scroll bar.

Check out the docs on multistage builds You have a COPY statement, and right after that a FROM statement. After that last statement you no longer have access to whatever was in there in previous stage. You can copy files from one stage to the next if needed with --from=stagename where you named the stage with FROM somerepo/someimage as stagename. In this case it means that everything you do in the first stage is never used or available again. Normally this is used something like

Your reactivity graph has too many edges, among other things.

For starters, DataRename depends on dataa() and input$file, but dataa already depends on input$file. So whenever input$file changes, both dataa and DataRename fire. Once dataa fires, then it triggers DataRename again. If you must have input$file in DataRename, then use isolate(input$file) there.

Further, DataRename looks at everything within input$, so ... whenever anything is updated in any input anywhere, DataRename is triggered. Therefore, everything downstream of DataRename is also triggered, even if unnecessarily.

dm also has a redundant dependency with corp and DataRename, where corp already depends on DataRename.

Another minor concern is that numComments references df, but I cannot find where it is defined in its view. Check to make sure you are not reaching out to the calling environment and finding a df hanging around. (If so, then this app may work locally but will fail when deployed.)

Possible fixes, untested:

The problem was the dashboardthemes package set a single background colour for all notifications even if they had a different status. I've fixed this in the latest v1.1.2 release of the package which is now available on GitHub. It will take several days to release on CRAN.

Found it! It was due to the following code:

The error message you are receiving is not Docker specific, but rather concerns your package manager apt.

Although you are updating the package list using apt-get update, you do not install newer versions of packages. What happens now is that you are trying to install a newer version of an already installed package which leads to the error message.

If you use apt-get upgrade, apt will install the newer versions of your installed packages.

Changing the 5th line as shown below will fix that issue:

RUN apt-get update && apt-get upgrade -y && apt-get install -y \

There are a few approaches you might try.

Easiest:

Use remotes::install_github instead of devtools. remotes has many fewer dependencies if you don't need the other functionality.

Second Easiest:

Use rocker/tidyverse image from Docker Hub instead of baseR image.

You can not put the dropdownButton in the dashboardHeader.

Instead you can put it in the dashboardBody or dashboardSidebar and have it updated like this :
