overwrite_by_regex: Modify existing object by regular expression

In roperators: Additional Operators to Help you Write Cleaner R Code

Modify existing object by regular expression

Description

This takes two arguments just like gsub - a patterns and a replacement. It will only overwrite the parts of any character where the pattern is matched with the second argument. If you want to overwrite whole elements via a regex (i.e. replace the entire element if it matches), use %regex<-% instead.

Usage

x %regex=% value

Arguments

x	a character vector
value	c(pattern, replacement)

Examples

# Apply a regular expression/substitution to x:

 x <- c("a1b", "b1", "c", "d0")

 # change any number to "x"

  x %regex=% c("\\d+", "x")

 print(x)

 # "axb" "b" "c" "dx"
