[julia-users] Re: How to assign names of a RArray object in Rif.jl?
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])
```

Hi,
There is a package NamedArray that attempts to make it possible to work
with named indices and dimensions in native Julia arrays, just like you are
used to in R. There is no interface to Rif.jl, though. Would this be a
useful extension?

I'm afraid the Rif.R("names<-") is not working.

Please open an issue on github. I will look at it. Thanks, L.
[julia-users] Re: How to assign names of a RArray object in Rif.jl?
I turns out that:
1- the error message is wrong (fixed in master)
2- it should be Rif.R("`names<-`")
3- better to open an issue on github than post on the list
4- the alternative (getrnames/setrnames) should now be the in latest
release of Rif. Just update.

I'd be happy to follow the naming convention for generics when handling
named arrays.

Quite good improvements. Thanks! I like getrnames and setrnames!, That's
much intuitive!

In Julia, I can create a RArray by
x=Rif.cR([1,2,3])
But anyone know how to assign the "names" to this RArray variable in
Julia?
