| I am using 'RcppArmadillo' for C++ coding. I am still not sure how to fix these above problems even though I went through the 'Writing R Extensions' document.  Could somebody help me fix these issues?

See this post from April 15 here on this list
  https://stat.ethz.ch/pipermail/r-package-devel/2019q2/003762.html
and my reply to it
  https://stat.ethz.ch/pipermail/r-package-devel/2019q2/003764.html

There is also a dedicated list for Rcpp* questions which may have
been more on-topic.
