Day 20 – little helper char_replace
This article is originally published at https://www.statworx.com/de/
We at STATWORX work a lot with R and we often use the same little helper functions within our projects. These functions ease our daily work life by reducing repetitive code parts or by creating overviews of our projects. At first, there was no plan to make a package, but soon I realised, that it will be much easier to share and improve those functions, if they are within a package. Up till the 24th December I will present one function each day from
helfRlein. So, on the 20th day of Christmas my true love gave to me…
What can it do?
This little helper replaces non-standard characters (such as the German umlaut "ä") with their standard equivalents (in this case "ae"). It is also possible to force all characters to lower case, trim whitespaces or replace whitespaces and dashes with underscores.
How to use it?
Let's look at a small example with different settings:
x <- " Élizàldë-González Strasse" char_replace(x, to_lower = TRUE)
 "elizalde-gonzalez strasse"
char_replace(x, to_lower = TRUE, to_underscore = TRUE)
char_replace(x, to_lower = FALSE, rm_space = TRUE, rm_dash = TRUE)
Have a merry advent season!
