ignore_case doesn't work for str_replace_all when using named vector

[alanault]

Hi,

I'm using str_replace_all with a named vector of patterns and replacements, so that they're all applied to a single character vector.

However, the ignore_case = TRUE argument seems to not have any effect:

# patterns and replacement
a <- c(apples = "fruit", pears = "fruit")

# test strings
test1 <- c("apples", "pears")
test2 <- c("APPLES", "PEARS")

# works; but doesn't need to ignore case
stringr::str_replace_all(test1, stringr::regex(a, ignore_case = TRUE))

# doesn't work 
stringr::str_replace_all(test2, stringr::regex(a, ignore_case = TRUE))

Is the ignore_case argument not meant to work when using a named vector, or is there another way I should be calling this?

many thanks
Alan
