I have a set of PNG files in a local folder, which I want to display in rshiny app under mainpanel. The code is very simple (referred from stackoverflow. The link for reference is here- Image slideshow in R Shiny - Stack Overflow).
My code -
library(shiny)
library(slickR)
it might well be there, but you aren't seeing it ? I experienced similar until I
a) change the backgrounds of different ui elements so you could see the slickr by contrast
b) put auto sliding behaviour on the slickr to see it moving without needing to find the buttons to move from one slide to the next.
sidenote. for my convenience I had some pngs in my working directory so I simplified the pathing to getwd().
