Unexpected behaviour when using str_replace() in string with a dot "."

[csrvermaak]

str_replace seems to randomly replace the first character when trying to replace a "." (might be piping related?)

strtest<-"TOP40TR.Index"
str_replace(strtest,".","X")

Expected:

[1] "TOP40TRXIndex"

Actual:

[1] "XOP40TR.Index"

This is a correct behavior, str_replace = stri_replace_first_regex, a regex . matches the first character (of any type)

Pardon my ignorance. Will read up on regex.

PS - How would I replace "." using str_replace()?

[gagolews]

fixed(.) AFAIR

Thanks Marek - but I don't quite understand :)

[csrvermaak]

Got it -

str_replace(strtest,"[.]","X")

How can i replace a part of a string like "from: abc@yahoo.com\n to: abc@gmail.com\n Hi all, \n"
replace "to: abc@gmail.com" with the string with ""

[Punitha89]

combination of substring() and gsub() helped me in solving the above issue. Thank you :)

str_replace(strtest,"[.]","X")

Thanks a bunch for this. I have struggled to find the solution for a week. Now I learned something new. Cheers!
