What I'm trying to do is exactly like what NSaunder's blog has done: Change a coloured cell in Excell into a category. However, I am using the readxl package whereas NSaunder's post uses the xlsx package. The xlsx package has a function called getCellStyle that returns a list of information that can be used to determine and recategorise cell colour. My question is: Is there a similar approach that can be used when using the readxl package?
Borrowing from NSaunder's blog, again, here is some example data.
