I was wondering how you would knit to word using an attached excel CSV file. When I try it says that the object is not found however I already processed it through with multiple tests. Does anyone know a solution?
It's really impossible to say what's going on without more detail. What does your source document look like? What do you mean by "excel CSV file"?
That being said, it smells like a path problem. Assuming we are talking about R Markdown, here are some troubleshooting tips, including some code you can insert to render through errors and reveal working directory and visible files.
