itp 1.2.1

The issue described at https://github.com/RcppCore/Rcpp/issues/1287has been fixed to avoid WARNINGs from CRAN checks on some platforms.Thank you to Dirk Eddelbuettel for providing the fix so quickly!

The argumentf to the functionitp() cannow be either an R function or an external pointer to a C++ function. Inthe latter case,itp() makes use of thePassinguser-supplied C++ functions framework offered by the Rcpp package.For the simple examples given in theitp package only amodest improvement in speed is observed (and expected). However, beingable to callitp() on the C++ side may have benefits inmore challenging problems.
The package vignette and README file include examples based onexternal pointers to a C++ function.
A plot method is provided, which plots the functionfprovided toitp over the input interval(a, b).

Explicit examples of passing arguments to the input functionf have been added.

A bug in the part ofitp() in which the bracketinginterval has been fixed. It caused incorrect results in cases where thefunction is locally decreasing.
Tests have been added to check the correction of this bug.
