Changing WD in RMarkdown

Question

My R Markdown script was running well until I had to access documents from another WD than my RMarkdown-file. I tried to change the WD. But it doesn't take it. I might access documents from different folder during my R Markdown Document. How can I be more flexible without coping my files into R Markdown folders? (that would be wasting space!)

Is this the right command?

knitr::opts_knit$set(root.dir = "C:/Users/Nadine/OneDrive/ZID_Kurse/Einführung/Kursmaterial")

And do I need to put it in the beginning of the document??? It just halts at the chunk with setWD() command.

Cheers, Nadine

You probably do not need to change the working directory; just explain where to find the files relative to the project working directory. You can use an absolute path to the files on the filesystem, e.g.

list.files("C:/projects/another_project/data/")

Or you may try to use relative paths to navigate to files through the parent directory. e.g.

list.files("../another_project/data/")
