this gets brought up again and again with no agreement and the only advice I know how to give you is that when working in any language that has mathematics as its primary focus (mathematica, matlab, Julia, R), you use 1-index, and other languages you use 0-index.

alilja's issue isn't 1-indexing, it's R's completely insane decision to return usable numerical values for an array access error. In Mathematica or Matlab accidentally using 0-indexing would lead to obvious errors, while in R it often doesn't - especially if you have sparse/many zero data already

That's not true. If you index with 0 you get a zero length vector back
