Replace Text between : and , to "X"

[anshuman_k]

Input :

My name : Harry, Age : 23, Address : London,

Need the output string to be :

My name : X, Age : X, Address : X,

[FJCC]

This can be done with str_replace_all from the stringr package.

S <- "My name : Harry, Age : 23, Address : London,"
library(stringr)
str_replace_all(S, ":[^,]+,", ": X,")
#> [1] "My name : X, Age : X, Address : X,"
