names2()
always returns a character vector, even when an
object does not have a names
attribute. In this case, it returns
a vector of empty names ""
. It also standardises missing names to
""
.
The replacement variant names2<-
never adds NA
names and
instead fills unnamed vectors with ""
.
names2(x)names2(x) <- value
A vector.
New names.
names2(letters)
# It also takes care of standardising missing names:
x <- set_names(1:3, c("a", NA, "b"))
names2(x)
# Replacing names with the base `names<-` function may introduce
# `NA` values when the vector is unnamed:
x <- 1:3
names(x)[1:2] <- "foo"
names(x)
# Use the `names2<-` variant to avoid this
x <- 1:3
names2(x)[1:2] <- "foo"
names(x)
