Scroll multiple graphs in one R chunk

[anastasiamiliopoulou]

I am trying to create a flexdashboard with one tab including multiple graphs (~50). What i get as an output is showing only some graphs and not all. The functionality of scroll is deactivated. I have tried to change the vertical layout = scroll but this does not work either. This seem to be related to the fact that all graphs are written in one chunk as produced by an in-chunk loop. Any ideas? Thanks

Can you separate each graph into its own chunk? You can achieve that with the knit_child() function to knit child documents inside the parent Rmd. See here: https://yihui.name/knitr/demo/child/

Thanks @bborgesr But the problem here is that number of graphs is unknown as it varies each time and that's why they're produced in a loop.

I see, you need to be able to create the chunks programmatically. I think these other resources will help you achieve that:
