Match a space character.

Matches a space character.

rx_space(.data = NULL, inverse = FALSE)

Arguments

.data	Expression to append, typically pulled from the pipe %>%
inverse	Invert match behavior, defaults to FALSE (match space). Use TRUE to not match space.

Examples

# match space, default
rx_space()
#> [1] " "

# dont match space
rx_space(inverse = TRUE)
#> [1] "[^ ]"

# create an expression
x <- rx_space()

# create input
string <- "1 apple\t"

# extract match
regmatches(string, regexpr(x, string))
#> [1] " "

# extract no whitespace by inverting behavior
y <- rx_space(inverse = TRUE)
regmatches(string, gregexpr(y, string))
#> [[1]]
#> [1] "1"  "a"  "p"  "p"  "l"  "e"  "\t"
