itp 1.2.1.9000

itp 1.2.1

CRAN release: 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

CRAN release: 2022-07-16

New features

• The function itp_c, which implements the ITP algorithm entirely in C++.

itp 1.1.0

CRAN release: 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

CRAN release: 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.
