Placeholders in powerpoint master layouts are not being consistently recognized by the officer package in R. In the example below I've attached a deck of 2 slides, each using a different master and layout. In the "title" layout, the placeholders display readily when layout_properties() is applied, but when I apply layout_properties() to "title and content" the output is 0 rows. This is a problem because in Powerpoint I can clearly see that there are 3 distinct placeholders in this layout. 

library(officer)
library(tidyverse)
library(magrittr)

file_deck <- "stack_demo.pptx"

deck <- read_pptx(file_deck)

layout_summary(deck)

layout_properties(deck, layout = "title", master = "intro") # outputs correctly
layout_properties(deck, layout = "title + content", master = "body") # incorrectly outputs "0 rows"

    I think you'd have better chance of solving your problem by asking on the package GitHub page https://github.com/davidgohel/officer/issues – Tung May 03 '18 at 19:00
  • @ Tung, it was a bug that has been fixed in the developer version of officer on github. – Joe May 03 '18 at 20:56
