- The formatting of 'x star' in the README file has been changed so that it renders correctly on GitHub.
- The issue described at RcppCore/Rcpp#1287 has been fixed to avoid WARNINGs from CRAN checks on some platforms. Thank you to Dirk Eddelbuettel for providing the fix so quickly!
- The function
itp_c, which implements the ITP algorithm entirely in C++.
- The argument
fto the functionitp()can now be either an R function or an external pointer to a C++ function. In the latter case,itp()makes use of the Passing user-supplied C++ functions framework offered by the Rcpp package. For the simple examples given in theitppackage only a modest improvement in speed is observed (and expected). However, being able to callitp()on the C++ side may have benefits in more challenging problems. - The package vignette and README file include examples based on external pointers to a C++ function.
- A plot method is provided, which plots the function
fprovided toitpover the input interval(a, b).
- Explicit examples of passing arguments to the input function
fhave been added.
- A bug in the part of
itp()in which the bracketing interval has been fixed. It caused incorrect results in cases where the function is locally decreasing. - Tests have been added to check the correction of this bug.
