R Markdown could not find function

Question

Running Compile Notebook from RStudio.

I am getting:

Error: could not find function "SegNeigh"

"SegNeigh" being my own function, properly sourced; the script runs fine without R Markdown.

Any help appreciated.

Answer 1

In order for the rmarkdown doc to find the function, you either need to define SegNeigh in the same document or place it in another file and source that file explicitly
