ZeroIfNA | R Documentation |
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.
ZeroIfNA(x)
NAIfZero(x)
NAIf(x, what)
BlankIfNA(x, blank="")
NAIfBlank(x)
Impute(x, FUN = function(x) median(x, na.rm = TRUE))
x |
