Dear Martin,
Does the work on nchar mean that bugs #16090 and #16091 will be resolved
[1,2]?
Thanks,

Sometimes the absence of a name is maked by an NA:
x <- 1:2
names(x)[[1]] <- "a"

Whereas other times its

Is this deliberate? The help for names() is a bit murky, but an
example shows the NA behaviour.

There is no inconsistency. Documentation of `names` says "...value
should be a character vector of up to the same length as x..."
In the first definition your character vector is not the same length
as length of x, so you enforce NA by not defining value[2]
x <- 1:2
value<-c("a")
value[2]
[1] NA
In `?names`:
If ‘value’ is shorter than ‘x’, it is extended by character ‘NA’s
to the length of ‘x’.
So it is as documented.
That said, it's somewhat surprising that both NA and "" serve as a
placeholder for a 'missing name'; I believe they're treated
identically by R under the hood (e
