ZeroIfNA: Replace NAs by 0

Description

Replace NAs in a numeric vector x with 0. This function has the same logic as the zeroifnull function in SQL. NAIfZero() does replace zeros with NA. BlankIfNA() and NAIfBlank() do the same, but for character vectors.

Usage

ZeroIfNA(x)
NAIfZero(x)
BlankIfNA(x, blank="")
NAIfBlank(x)
Impute(x, FUN = function(x) median(x, na.rm = TRUE))

Arguments

x

the vector x, whose NAs should be overwritten with 0s.

blank

a character to be used for "blank". Default is an empty string ("").

FUN

the name of a function to be used as imputation. Can as well be a self defined function or a constant value. Default is median.

Value

the edited vector x

Examples

# NOT RUN {
z <- c(8, NA, 9, NA, 3)

ZeroIfNA(z)
# [1] 8 0 9 0 3

Impute(z)
# [1] 8 8 9 8 3


z <- c("a", NA, "", NA, "k")

BlankIfNA(z)
# [1] "a" "" "" "" "k"
# }
