I'm using the officer package in R, and I have a lot of charts on a slide. To break up the slide, I want to add a shape in between them (think, a long narrow rectangle). I know I could save something as an image and put it in, but this code is meant to be shared broadly. Thus, it'd be much easier if I could tell R to use a PowerPoint shape rather than upload my own image.
Is this possible? Or, is there some other workaround that doesn't involve creating a custom shape, saving it as an image, and uploading it from my computer?
