How to extract the second part of the string after the backslash in R?

Question

I have a string 'ABC1\001ABCEFCGJS' I want to extract only 001ABCEFCGJS from this string How to do so in R? My String will be a dynamic string. So the solution should be such that function can read anything after backslash.

Answer 1

One option would be to convert to raw and then remove the elements, while appending the correct raw value for '001'

rawToChar(c(charToRaw('001'),charToRaw(str1)[-(1:5)]))
#[1] "001ABCEFCGJS"

data

str1 <- 'ABC1\001ABCEFCGJS'
