I am using Reporters package to generate pptx document in a shiny app.
In here there is some explanation of how to add external image to document by Reporters package. But I could not find a solution to import leaflet map to pptx via reporters. Any examples or information would be very much appreciated.
Leaflets are designed to be displayed in web pages (as htmlwidgets), this format is not supported by ReporteRs.
You can embed a screenshot of the leaflet (as an image) with webshot. See https://cran.r-project.org/web/packages/webshot/vignettes/intro.html
