Removing words featured in character vector from string

Question

I have a character vector of stopwords in R:

stopwords = c(\"a\" ,
            \"able\" ,
            \"about\" ,
            \"above\" ,
            \"abst         


        

Answer 1

Try this:

str <- c("I have zero a accordance")

stopwords = c("a", "able", "about", "above", "abst", "accordance", "yourself",
"yourselves", "you've", "z", "zero")

x <- unlist(strsplit(str, " "))

x <- x[!x %in% stopwords]

paste(x, collapse = " ")

# [1] "I have"

Addition: Writing a "removeWords" function is simple so it is not necessary to load an external package for this purpose:

removeWords <- function(str, stopwords) {
  x <- unlist(strsplit(str, " "))
  paste(x[!x %in% stopwords], collapse = " ")
}

removeWords(str, stopwords)
# [1] "I have"
