str_replace_all() changes all of the string

I am working on a character variable which I want to change the dots "." in it to underscore "". But when I enter the code, it changes all of the character to "______". I tried changing "A"s to "E"s which worked but I could not make it work for dots and underscore.

x <- "TP.MK.CUM.YTL"
y <- str_replace_all(x, ".", "_")

y
# [1] "____________"

Wrap with fixed as . is special character to match any character

library(stringr)
str_replace_all(x, fixed("."), "_")
[1] "TP_MK_CUM_YTL"

Or use chartr in base R

chartr(".", "_", x)
[1] "TP_MK_CUM_YTL"
