remove multiple patterns from text vector r

Question

I want to remove multiple patterns from multiple character vectors. Currently I am going:

a.vector <- gsub("@\w+", "", a.vector)
a.vector <- gsub("http\w+", "", a.vector)
a.vector <- gsub("[[:punct:]], "", a.vector)

etc etc.

This is painful. I was looking at this question & answer: R: gsub, pattern = vector and replacement = vector but it's not solving the problem.

Neither the mapply nor the mgsub are working. I made these vectors

remove <- c("@\w+", "http\w+", "[[:punct:]]")
substitute <- c("")

Neither mapply(gsub, remove, substitute, a.vector) nor mgsub(remove, substitute, a.vector) worked.

a.vector looks like this:

[4951] "@karakamen: Suicide amongst successful men is becoming rampant. Kudos for staing the conversation. #mental"

Answer 1

I know this answer is late on the scene but it stems from my dislike of having to manually list the removal patterns inside the grep functions (see other solutions here). My idea is to set the patterns beforehand, retain them as a character vector, then paste them (i.e. when "needed") using the regex seperator "|":

library(stringr)

remove <- c("@\w+", "http\w+", "[[:punct:]]")

a.vector <- str_remove_all(a.vector, paste(remove, collapse = "|"))

Yes, this does effectively do the same as some of the other answers here, but I think my solution allows you to retain the original "character removal vector" remove.
