rcpptimer 1.2.1

Fixes

• This release fixes a bug where calling .toc() on a timer that was already stopped would cause a signed integer overflow. This a minor change in CppTimer as well as Rcpp::Timer.

rcpptimer 1.2.0

Improvements

• The stop() method of Rcpp::Timer now returns a data.frame with the results. This is useful if you want to set auto return to false and manually handle the results. It is also possible to call aggregate() and access the public variable data of Rcpp::Timer. data is a map containing the results (Names, Mean, Standard Deviation, Count). Look into the implementation of stop() in “inst/rcpptimer.h” to see how this works.
• The tag arguments of tic(), toc() and ScopedTimer() have default values now.
• The existing vignette was updated, and we added four new vignettes to the package.
• rcpptimer now measures nanoseconds instead of microseconds.
• Adds print.rcpptimer method to print the results of a timer object. Timings will be scaled to a more readable unit (e.g. milliseconds, seconds, minutes, hours) when appropriate.
• Warn about timers for which .toc() was called more than once.
• The summary now includes the minimum and maximum times.

Internal Changes

• Added lots of tests to cover 100% of the code.
• Public member “name” was moved from CppTimer to Timer as it is R-specific.
• Add a hex sticker to the package.
• The package now has a documentation entry (?rcpptimer).
• Various improvements to the underlying CppTimer class

rcpptimer 1.1.0

Improvements

• Add new Rcpp::CppTimer::ScopedTimer class. This can be used to time the lifespan of an object until it goes out of scope. This is useful for timing the duration of a function or a loop. The fibonacci example was updated to use this new class.
• Warn about timers that are not stopped when aggregate is called (no matching toc() statement).
• Warn about timers for which no matching tic() statement was found.
• Add verbose parameter to the Timer class to control whether above warnings should be printed or not (defaults to true).
• Add introductory vignette to the package.

Fixes

• Fixed cases where only toc() was called without matching tic().
  • This led to a segfault in the previous version.
• Fix reset() method which was not working properly in some cases where timers spread out over multiple methods.
• Fix non-default constructors of the Timer class. They were not working properly in the previous version.

rcpptimer 1.0.0

This is the initial release of rcpptimer. It is based on RcppClock but contains a number of improvements:

• OpenMP support
• Automatically returns results to R as soon as the C++ Object goes out of scope
• Fast computation of Mean and Standard Deviation of the results in C++
• Uses tic and toc instead of tick and tock to be consistent with R’s tictoc package
• Always reports microseconds resolution
• Many more performance improvements

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
