r - Can you change the name of an element on an array without trying to set the names of the entire array?

Question

I was recently surprised to find that the following didn't work:

output<-array(1:10)
names(output[1])<-"Foo"

As far as I can tell, this does not changes the name of output[1]. Is it possible to modify the names of the individual elements of an array like this? Or am I forced to write code that modifies the entire array, like names(output)<-c("foo",rep(NA,9))?

Answer 1

You want to change the first name of an element, so [1] goes outside names(output):

output<-array(1:10)
names(output)[1]<-"Foo"
names(output)
#>  [1] "Foo" NA    NA    NA    NA    NA    NA    NA    NA    NA
