R Script not working as expected

Hi all,


I'm faced with the following problem:

I have a list of website pages, which I would like to group in different content groups based on regex matching. The only way to set this up in the Query Editor is via an R Script. This is how I set it up:



# 'dataset' holds the input data for this script
filter <- "(www\\.simscale\\.com\\/|www\\.simscale\\.com\\.googleweblight\\.com\\/)blog\\/(.*)"

# Define Functions
checkComp <- function(f) {grepl(f , as.character(dataset$"Initial Landing Page"),}

returnComp <- function() {
	if (checkComp(filter)) {
		result <- "Blog"
	} else {
		result <- "Other"

output <- within(dataset,{"Test"=returnComp()})


dataset$"Initial Landing Page" is the column that contains the page URL.


The problem is that the returnComp() function always returns "Other". I tried everything. Testing this function in an online R tester works as expected. Just in PowerBI it doesn't work. There seems to be an issue when I pass the column to the function. But I don't know what else to try.


The column containsthe URLs in plain text, like this:

Add a custom function and invoke it for each row.
