irregular2v: Replace "Irregular" Values of a Vector with Some Other Value

Description

Check a vector for the presence of "irregular" values (e.g., NA) and, if found, replace with some other (single) user-specified value.

Usage

irregular2v(
  x,
  to = 99,
  nan.include = TRUE,
  inf.include = TRUE,
  special = c("NA", "NAN", "INF", "-INF"),
  other = NULL
)

Value

a vector identical to x, with exception that NA (and other irregular) values have been converted to the value specified in "to" argument.

Arguments

x

a vector.

to

a single value to which all NA (and other irregular) values should be converted (Note: if arg is character, returned vector will be coerced to character).

nan.include

treat NaN values as NA.

inf.include

treat Inf and -Inf values as NA.

special

a modifiable set of default character values that will be treated as equivalent to NA values.

other

additional user-specified values (of consistent class) that will be treated as equivalent to NA values.

Details

For purposes of irregular2v, irregular values consist of: NA values, other arbitrary values you specify, and (by default): NaN, Inf, -Inf, and character variants of same (i.e., upper, lower, or mixed-case variants of "NA","NAN", "INF","-INF"). This function is used insider core labelr functions to manage such values, but the typical labelr user will have no explicit need to use it as part of an interactive session.

Examples

set.seed(123)
x <- c(NA, Inf, -Inf, NaN, runif(6))
x
x1 <- irregular2v(x, to = 33)
x1

set.seed(123)
x1 <- c(NA, Inf, -Inf, NaN, runif(6))
x
x1 <- irregular2v(x, to = 33, nan.include = TRUE, inf.include = FALSE)
x1

set.seed(123)
x <- c(NA, "INF", "in", "nan", "NA", sample(letters, 5))
x
x1 <- irregular2v(x, to = "<-X->")
x1
