Extract part of string between two different patterns

Question

I try to use stringr package to extract part of a string, which is between two particular patterns.

For example, I have:

Answer 1

You can use the package unglue:

library(unglue)
my.string <- "nanaqwertybaba"
unglue_vec(my.string, "nana{res}baba")
#> [1] "qwerty"
