impute-constant: Impute by Constant Value

Replaces NAs by a constant

Description

Impute by Constant Value

Replaces NAs by a constant

Usage

na.constant(.x, .na)
na.inf(.x)
na.neginf(.x)
na.true(.x)
na.false(.x)
na.zero(.x)

Arguments

.x

vector; of values to have the NA

.na

scalar to use as replacement.

Value

A vector with the type and length of x with all missing values replaces by .na.

Details

These functions replace ALL NA values in x with an scalar value specified by.na.

na.constant replaces missing values with a scalar constant. It is a wrapper around na.replace() but permits .na to only be a scalar.

na.inf and na.neginf replace all missing values with Inf and -Inf repectively. `.

na.true and na.false replace missing values with TRUE and FALSE respectively.

na.zero replaces missing values with 0 which gets coerced to the class(x) as needed.

See Also

• na.replace() the underlying function that performs the replacement.

Examples

# NOT RUN {
  na.constant( c(1,NA,2), -1 )
 
  na.inf( c( 1, 2, NA, 4) )
  na.neginf( c( 1, 2, NA, 4) ) 
  
  na.true( c(TRUE, NA_logical, FALSE) )   # T T F
  na.false( c(TRUE, NA_logical, FALSE) )  # T F F

 
           
  na.zero( c(1,NA,3) )  # 1 0 3 

 
           
# }
