Filter a column which contains several keywords

Question

I am trying to filter a column which contains several keywords (in this example dog and cat) but I am having problems as only the first element is being used.

Answer 1

Here is a dplyr method:

library(stringi)
library(dplyr)

data = data_frame(
  id = c(1:7),
  type = c("dog1","dog2" ,"cat1","cat2","zebra1", "parrot5", "elephant15")
)


data %>%
  filter(animals %>%
           paste(collapse = "|") %>%
           stri_detect_regex(type, . ) )
