irregular2v {labelr} | R Documentation |
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
)
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.
Value
a vector identical to x, with exception that NA (and other irregular) values have been converted to the value specified in "to" argument.
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
