Question

I find myself often writing the following two lines. Is there a succinct alternative?

      newObj  <- vals
names(newObj) <- nams

# This works, but is ugly and not necessarily preferred
'names<-'(newObj <- vals, nams)

I’m looking for something similar to this (which of course does not work):

newObj <- c(nams = vals)

Wrapping it up in a function is an option as well, but I am wondering if the functionality might already be present.

sample data

vals <- c(1, 2, 3)
nams <- c("A", "B", "C") 

Answer 1

You want the setNames function

# Your example data
vals <- 1:3
names <- LETTERS[1:3]
# Using setNames
newObj <- setNames(vals, names)
newObj
#A B C 
#1 2 3
