How to match a vector to a dataframe using mutate-CodePudding

I have a data frame in which I'd like to make a new column which is set to TRUE or FALSE depending on whether it matches with a vector.

So far I've tried two different approaches, the first directly using the %in% operator to check whether elements of test occurred in column apples, the second by putting this in an ifelse statement.

test <- c("a","b","c")
df <- tibble(apples = c("a","d","e","f","z","g","c"))

#First attempt
df_match <- df %>% 
  mutate(
    match = test %in% apples
  )

#Second attempt
df_match <- df %>% 
  mutate(
    match = ifelse(test %in% apples,TRUE,FALSE)
  )

The desired output for column 'match' would be

> df$match
[1] TRUE FALSE FALSE FALSE FALSE FALSE TRUE

Using base R

 transform(df, match = apples %in% test)
