How to source() an external R script using Quarto?

Question

I'm trying out Quarto and 'converting' my Rmarkdown file into a quarto document. In my old Rmarkdown file, I would use source("R_datacleaning.R") and source("R_Functions.R") to run the data cleaning and to load some functions. I've also tried source(here("R_Functions.R")) but it doesn't work either. The R-scripts and the qmd files are in the same directory.

I can't seem to get that to work in the .qmd. The error I get is Error: RStudio not running. I've searched around and looked at the Quarto documentation, but couldn't find anything relating to this. I think there might be something I'm not understanding about the Quarto environment in RStudio. Would appreciate any help, thanks!

Edit:

---
title: "quarto_test2"
format: html

```{r}
library(here)

source(here("R_Functions.R"))
```

Error message is:

R_Functions.R is in the same directory as quarto_test2.qmd, as previously mentioned.
