Result 1 is not a length 1 atomic vector

[Btibert3]

I am starting to get into building slide decks in RMD, and came across this package in the wiki for xaringan.

Below is the error that I am seeing:

Error in convert_pptx(path = "test-ppt-slidex2.pptx", author = "Brock Tibert") : 
  Result 1 is not a length 1 atomic vector

I see #16, and this is the original build process I started with (built in Google Slides -> PPT), but the file above, was opened in PPT locally and saved with a different name. I was hoping that would fix it.

Thanks! My guess is you’ll need to use the dev branch but it is rather unstable for other reasons. I have had no time to develop this in recent months, unfortunately. But I will try to look into this soon.

[Btibert3]

Thanks, I will take a look. This is a fantastic idea for a package.

I tried to convert PowerPoint slides to xaringan slides but I got the same error as Btibert3: "Result 1 is not a length 1 atomic vector " :/.

Thanks! Can you attach the powerpoint you were having issues with? I have not had time to work on this package for quite some time but hoping to resume at least support-level development soon. I might be able to have time to address this if you can share the slides that are causing the issue.

This is one of the powerpoint file that I've tried to convert: TalkaboutR.pptx. Also I tried with others pptx but it didn't work neither. Thank you so much for your time!

[datalorax]

So I'm not closing this issue because it still needs some work but it should basically work if you install from the newbullets branch:

remotes::install_github("datalorax/slidex@newbullets")

(but please let me know if it still doesn't render)

[PatriLoto]

Yesss, it work . I've just convert my pptx file but only one thing didn't work, the Powerpoint images are not coming across into the img folder. Anyway, I read the issue #15 and I'm resolving to copy the images from powerpoint file to the img sub-folder. Thank you very much again :)

[datalorax]

Great! Glad at least that part was resolved. Good luck!
