Currently the way to do is to explicitly call the R-level setter:
x = Rif.R("names<-")(x, Rif.cR("A", "B", "C"))
However, as of today commit the C-level is exposed and a way that is
looking a little more like native Julia.
(I'll do a pull request so this is part of the released package soon).
The unit-tests are for vectors, and should be explict:
https://github.com/lgautier/Rif.jl/blob/master/test/vectors.jl#L57
```julia
# The C API for R has specialized MACRO for names getrnames/setrnames
# exposes it
vi2 = Int32[1,2,3]
rvi2 = Rif.RArray{Int32,1}(vi2)
@test isequal(None, Rif.getrnames(rvi2))
Rif.setrnames!(rvi2, Rif.RArray{ASCIIString,1}(ASCIIString["a", "b", "c"]))
@test isequal("a", Rif.getrnames(rvi2)[1])
@test isequal("b", Rif.getrnames(rvi2)[2])
@test isequal("c", Rif.getrnames(rvi2)[3])
# setAttr/getAttr will be equivalent
vi2 = Int32[1,2,3]
rvi2 = Rif.RArray{Int32,1}(vi2)
@test_throws ErrorException Rif.getAttr(rvi2, "names")
Rif.setAttr!(rvi2, "names",
Rif.RArray{ASCIIString,1}(ASCIIString["a", "b", "c"]))
@test isequal("a", Rif.getAttr(rvi2, "names")[1])
@test isequal("a", Rif.getrnames(rvi2)[1])
@test isequal("b", Rif.getAttr(rvi2, "names")[2])
@test isequal("b", Rif.getrnames(rvi2)[2])
@test isequal("c", Rif.getAttr(rvi2, "names")[3])
@test isequal("c", Rif.getrnames(rvi2)[3])
```
