Usage in flexdashboard and runtime shiny

[dirkdegel]

Hi all, I'm totally new to this package and it is something I was looking for for a while.

I found this article: https://www.r-bloggers.com/shinymatrix-matrix-input-for-shiny-apps/ and used the code to build the app.R file and it worked perfectly fine.

Usually I use flexdashboards with the shiny runtime. I tried to use the same code but was not able to get it running. Please find a minimal example below.

Any help is much appreciated.

Thanks Dirk

  inputId = "sample", 
  value = m,
  #inputClass = matrix-input,
  rows = list(extend = TRUE), 
  cols = list(names = TRUE),
  class = "numeric",
  paste = TRUE,
  copy = TRUE
)

})

Flexdashboard + runtime shiny has been very buggy in my experience. Try replicating in a regular shiny app?

Hi @dirkdegel

thanks for reporting this. I am not sure how flexdashboard includes the javascript and css files. Could you post the page source from the flexdashboard page to see if the shiny-matrix dependencies are included at all?

I also tried to reproduce this. The <div> section created by shinyMatrix is actually included in the output of your flexdashboard (you can see it, when using the "Inspect element"). However it's not properly displayed in the HTML. It seems indeed, that shinyMatrix and flexdashboard are not compatible. It will require modifications in one of the two packages to make it work.

I am closing this because it seems like a flexdashboard issue.
