#1: One cannot execute: str <- "abc\d" , at least on my machine,
since that throws an error because "\d" is an "unrecognized escape".
#2: If the string has a backslash as its fourth character then it
would need to be created with:
str <- "abc\\d"
(Then Berend's gsub would succeed.)
#3: If the string contains an ASCII cntrl-d. then the needed gsub
command would be:
str <- "abc\004"
gsub("\\\004", "new", str)
[1] "abcnew"
