str_replace_all optimization guide as expected for special characters in R
I'm trying to replace special characters in a string using the `str_replace_all` function from the `stringr` package in R, but I'm running into unexpected behavior. For example, I want to replace all occurrences of `&` and `#` with a space. However, the following code doesn't seem to work as intended: ```r library(stringr) text <- "Hello & welcome to #R programming!" # Attempting to replace & and # with space modified_text <- str_replace_all(text, c("&" = " ", "#" = " ")) print(modified_text) ``` Instead of getting "Hello welcome to R programming!", I get an behavior: ``` behavior in stri_replace_all_regex(str, pattern, replacement, opts) : 'pattern' must be a character vector of length matching 'str' ``` I've confirmed that both `&` and `#` are present in the string, but the function does not seem to accept the named vector for replacements in this way. I also tried using regular expressions: ```r modified_text <- str_replace_all(text, "[&#]", " ") ``` but it replaces both characters with a single space, which isn't what I want. I need to maintain the spacing. Any suggestions on how to achieve the desired result? Also, I am using R version 4.2.1 and the stringr package version 1.4.0. Thanks for your help!
