Hello;
The results with the code you suggested below do not work. So, I can't download the word file when I run the codes. I want the code to run as ist NULL ın if the conditions are provided. But I don't want this istem NULL asında output to appear on the word page. I'd appreciate it if you could help me with that.
I don't really follow this question. There seems to be a pretty big disconnect between the issues you write about and the rmarkdown code provided.
I would really encourage you to review the following guide, FAQ: Tips for writing R-related questions.
For example, the guide emphasizes asking coding questions with a reprex. You may have noticed that many people here request issues come in the form of a minimal reprex, that's because asking questions this way saves answerers a lot of time helping you get your issue resolved.
