stringr 1.3.0 - stringr provides a cohesive set of functions designed to make working with strings as easy as possible.

February 21, 2018

We are happy to announce that stringr 1.3.0 is now on CRAN. stringr provides a cohesive set of functions designed to make working with strings as easy as possible. For a complete list of changes, please see the release notes.

What’s new?

  • Two new wrappers from the glue package: str_glue() and str_glue_data(). If you haven’t heard of glue, you’re in for a treat! Glue lets you easily interpolate data into strings.

    name <- "Chet Manley"
    str_glue("My name is {name}.")
    #> My name is Chet Manley.

    Since stringr is loaded with tidyverse, this means that you can now access glue’s functionality without loading another package.

  • str_flatten(), a wrapper for the stri_flatten() function, which flattens a character vector into a single string. This is equivalent to paste(x, collapse = "-") but it is a bit more explicit in your code – str_flatten() always returns a single string.

  • str_remove() and str_remove_all(), which wrap str_replace() and str_replace_all() for removing patterns from strings.

  • str_squish(), which removes whitespace from the left and right sides of strings, and converts multiple spaces or space-like characters from the middle of strings into a single space.

    str_squish("\n\nString \t\nwith all \tthis     \rspace   in it.\n\n")
    #> [1] "String with all this space in it."

API changes

The long deprecated str_join(), ignore.case(), and perl() functions have been removed. You may see Error : object ‘ignore.case’ is not exported by 'namespace:stringr' during package build.
