difference between two strings (str_diff)

[ctmann]

It would be helpful to have a function that shows the difference between two strings, as:

x <- "a sample, etc"
y <- "a sample etc"

  
  str_diff <- function(x,y){
    setdiff(stringr::str_split(x[[1]], "")[[1]], 
                     str_split(y[[1]], "")[[1]] 
    )
  }
  
str_diff(x,y)

> str_diff(x,y)
[1] ","

Doing this well is hard, so is outside the scope of stringr. You might try diffobj instead.
