itp 1.2.2 (2026-01-10)
Bug fixes and minor improvements
- Implements the patch described in Rcpp Issue #1406 to avoid masking of
Rf_error().
- The formatting of 'x star' in the README file has been changed so that it renders correctly on GitHub.
- A minor typo (missing "If" in "If the root ...") has been corrected in the Value section of the
itp() help file.
itp 1.2.1 (2023-12-02)
Bug fixes and minor improvements
- The issue described at https://github.com/RcppCore/Rcpp/issues/1287 has been fixed to avoid WARNINGs from CRAN checks on some platforms. Thank you to Dirk Eddelbuettel for providing the fix so quickly!
itp 1.2.0 (2022-07-16)
New features
- The function
itp_c, which implements the ITP algorithm entirely in C++.
itp 1.1.0 (2022-07-02)
New features
- The argument
f to the function itp() 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 the itp package only a modest improvement in speed is observed (and expected). However, being able to call itp() 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
f provided to itp over the input interval (a, b).
Bug fixes and minor improvements
- Explicit examples of passing arguments to the input function
f have been added.
itp 1.0.1 (2022-06-14)
Bug fixes and minor improvements
- 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.
