Add Rcpp Integration

Integrate C++ code into an R package using Rcpp for performance-critical operations.

When to Use

• R function is too slow and profiling confirms a bottleneck
• Need to interface with existing C/C++ libraries
• Implementing algorithms that benefit from compiled code (loops, recursion)
• Adding RcppArmadillo for linear algebra operations

Inputs

• Required: Existing R package
• Required: R function to replace or augment with C++
• Optional: External C++ library to interface with
• Optional: Whether to use RcppArmadillo (default: plain Rcpp)
