Chaining string manipulation with multiple patterns and multiple designated replacements

I would like to change multiple strings in a variable with multiple replacements. Preferably with for example stringrbecause qdap has a lot of dependencies and I can't get it to work. I'm inclined to think something like the following should work, but it doesn't. Also not when escaping the string brackets or dots with \\.

library(stringr)

data <- c("Partij van de Arbeid (P.v.d.A.)", 
          "VVD",
          "GROENLINKS", 
          "Democraten 66 (D66)")

str_replace_all(data, c("Partij van de Arbeid (P.v.d.A.)",
                        "GROENLINKS",
                        "Democraten 66 (D66)"),
                c("PVDA", 
                  "GL", 
                  "D66"))

Wanted output:

> data
[1] "PVDA" "VVD"  "GL"   "D66"

Why can't you make `mgsub` work? What have you tried? – Wiktor Stribiżew Jun 17 '18 at 14:33
