I have an output that I receive from a Shiny app i'm building. The output looks like this:

[1] "wrong item"       "Wrong order"      "completely wrong"

it appears to be tab delimited but i'm not event sure of the format. I would need to be able to convert it to a pipe delimited list such as

df %>% 
    filter(str_detect(string, wrong item|Wrong order|completely wrong"))

is it possible at all? As a starting point I've tried to convert the output to a list but it's not letting me as there's no comma:

l<-paste("wrong item"       "Wrong order"      "completely wrong")

Thank you if you can help me it would be much appreciated.

I think you need something like this?:

#If your output is x
x <- c("wrong item", "Wrong order", "completely wrong")

paste(x, collapse = "|")
# will give:
# [1] "wrong item|Wrong order|completely wrong"


# so in your example it could be: 

library(dplyr)
library(stringr)

df %>% 
  filter(str_detect(string, paste(x, collapse = "|")))

# OR 

df %>% 
  filter(str_detect(string, paste(c( "wrong item", "Wrong order", "completely wrong"), collapse = "|")))
