I have an R library (using Rcpp) that used to compile and install fine.
It uses some boost libraries. My Makevars file looks like this:
PKG_LIBS=`$(R_HOME)/bin/Rscript -e "Rcpp:::LdFlags()"` -lboost_iostreams -lm
CXX_STD = CXX14
The problem I face now is that for some other R-independent softwa
Thanks for the hint. I think I will use a big.matrix [with 1 element
only ;-) ] and a mutex to ensure access is thread-safe.

In aov and lme, this is possible with terms(..., keep.order=TRUE).
