[Rcpp-devel] Maximum Columns in Rcpp DataFrame (revisited)

[Steffen Neumann]

Hi,

I (think I) need to create a DataFrame with more than 20 entries,
because I want another slot in this file:
https://github.com/sneumann/mzR/blob/master/src/RcppRamp.cpp#L221

I stumbled upon a 2year old answer here:

http://lists.r-forge.r-project.org/pipermail/rcpp-devel/2013-March/005430.html

Questions: 

1) Should I avoid DataFrame here in first place ? I'd love to keep it
2) Is there a more elegant solution for >20 entries by now ?
3a) How do I create the mentioned "local header file with 21, 22, 23, ... \infty arguments as you need it."
3b) How and where do I #include that ? I need to fake a directory structure 
    so that <Rcpp/DataFrame.h> picks up my version of #include <Rcpp/generated/DataFrame_generated.h> ?
4) Is that future proof ?!

Thanks in advance,
Yours,
Steffen
