Modify an object in place by regular expression

Source: R/operators.R
overwrite_by_regex.Rd

This takes two arguments, just like gsub: a pattern and a replacement. It overwrites only the matched portion of each element of x. If you want to overwrite whole elements that match (rather than just the matched portion), use %regex<-% instead.

Usage

x %regex=% value

Arguments

x

a character vector

value

a length-2 character vector of the form c(pattern, replacement)

Value

Used for the side effect of reassigning x in the calling environment; returns the modified x invisibly.

Examples

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

# change any digit to "x"
x %regex=% c("\\d+", "x")
print(x)
#> [1] "axb" "bx"  "c"   "dx" 
# "axb" "b" "c" "dx"
