officedown::rpptx_document 를 사용하여 Rmd 파일을 편직하면 이 함수는 다음 오류 메시지와 함께 열 수 없는 pptx 파일을 생성합니다.

PowerPoint found a problem with content in xxxx.pptx.
PowerPoint can attempt to repair the presentation.

Rmd의 내용이 eaxample의 경우 bookdown::powerpoint_presentation2 로 편직 가능함을 확인했습니다. 따라서 officedown::rpptx_document 에 일부 버그가 있을 수 있습니다.
