Example not working

[SarithaKodikara]

Hi,
This is a great tool for highlighting R source code, which is useful for training new R users. It is exactly what I was looking for! However, I am wondering if the package still works, as the highlights do not appear when I run the example provided in the vignette with the R version 4.3.2.
