vtrace

An R package for collecting information about how vectors and data frames are used in R programs.

See the vtrace-analysis "meta" repository for details on how to develop and use this package.

Architecture

• R/ - R source code
  • R/tracer.R - Main application code, in R
• src/ - C++ source code
  • src/callbacks.{h,cpp} - Main application code, in C++
• src/model - Models R objects in the tracer -- these need to be header-only

Boilerplate

• src/init.c - Registers native functions so they can be called from R
• src/r_callbacks.{h,cpp} - Wrapper functions that return R pointers to C++ functions

Libraries

• src/lib/picosha2.h - PicoSHA2 is a small, header-only, C++ library for generating SHA256 hashes
