r - Remove a list of whole words that may contain special chars from a character vector without matching parts of words

Question

I have a list of words in R as shown below:

 myList <- c("at","ax","CL","OZ","Gm","Kg","C100","-1.00")

And I want to remove the words which are found in the above list from the text as below:

 myText <- "This is at Sample ax Text, which CL is OZ better and cleaned Gm, where C100 is not equal to -1.00. This is messy text Kg."

After removing the unwanted myList words, the myText should look like:

  This is at Sample Text, which is better and cleaned, where is not equal to. This is messy text.

I was using :

  stringr::str_replace_all(myText,"[^a-zA-Z\s]", " ")

But this is not helping me. What I should do??

Answer 1

gsub(paste0(myList, collapse = "|"), "", myText)

gives:

[1] "This is  Sample  Text, which  is  better and cleaned , where  is not equal to . This is messy text ."
