requiring Rcpp 0.10.6.2 so that you get the last fix that meant undoing Rmath macros early enough.

I've also changed functions so that they use attributes ([[Rcpp::export]])

[romainfrancois]

Hmm. I need to fix .Call calls first.

[romainfrancois]

ok so there was a corner case because Rcpp::exporting fastLm is creating a fastLmR function as part of the attributes business, so I've renamed the internal one fastLm_impl

[romainfrancois]

travis is happy now. @dmbates I'll leave it to you to merge this if you like.

@romainfrancois Which version of Rcpp should I be testing this with? I have installed the current master branch (9c5babc) and consistently get failures of the tests of the form

>   flm <- fastLmPure(mm, y)
Error in fastLm_impl(X, y, as.integer(method[1])) : 
  function 'enterRNGScope' not provided by package 'Rcpp'
Calls: fastLmPure -> fastLm_impl -> .Call

[romainfrancois]

I'll have a look. I should probably review in which namespace was each function before and put it in the same place.

but at least it works with released Rcpp (in travis it built).

I corrected the .travis.yml in the headeronly branch to use Rcpp from Github; it fails with the very issue @dmbates noted here, see https://travis-ci.org/RcppCore/RcppEigen/builds/14053890

[romainfrancois]

So:

>   flm <- fastLmPure(mm, y)
Error in fastLm_impl(X, y, as.integer(method[1])) : 
  function 'enterRNGScope' not provided by package 'Rcpp'
Calls: fastLmPure -> fastLm_impl -> .Call
Execution halted

That type of message would appear if the Rcpp has not been loaded, i.e. the R_init_Rcpp function has not been called.

I'm trying using Depends: Rcpp, or perhaps we can use useDynLib(Rcpp) in RcppEigen's namespace,

[romainfrancois]

This closes the enterRNGScope problem, but has opened another set of issues;
https://travis-ci.org/RcppCore/RcppEigen#L1296

[romainfrancois]

Probably irrelevant now.

[eddelbuettel]

Yes.

RcppEigen is among the 157 out of 166 [ numbers as of now ] packages who work 'as-is'. See the rcpp-logs repository for details.
