numDeriv 2022.9-1
- Changed license from GPL-2 to GPL >= 2.
numDeriv 2020.2-1
- Fixed Rbuildignore so that files from building vignettes are
not omitted in the package build.
- Added German translation of messages (provided by Chris Leick).
- Added Korean translation of messages (provided by Chel Hee Lee).
numDeriv 2016.8-1 (2016-08-27)
- simplification of hessian.default() call to jacobian() and grad()
in the case of method 'complex' (pointed out by Andreas Rappold).
- added argument 'side=NULL' in the hessian.default() call to jacobian()
and grad() in the case of method 'complex' to ensure proper passing
of ... arguments to the function for which the hessian is being
calculated (pointed out by Andreas Rappold).
numDeriv 2014.2-1 (2015-05-04)
- added argument 'side' to allow one-sided first derivatives (grad and
jacobian) for simple and Richardson methods.
- minor documentation improvements.
numDeriv 2013.2-1
- updated R dependency from 1.8.1 to 2.11.1 because of complex step
derivative dependency on a fix to exponentiation with integers (pointed
out by Hans W. Borchers).
- added flag in DESCRIPTION to ByteComple.
numDeriv 2012.9-1 (2012-10-14)
- added complex step derivatives (from Ravi Varadhan) and related tests.
- changed method.args to an empty list in the default methods, as the real
defaults depend on the approximation, and are documented in details.
numDeriv 2012.3-1 (2012-03-27)
- no real changes, but bumping version for new CRAN suitability check.
numDeriv 2011.11-2
- fixed genD documentation error for denominator in f" (d^2 rather
than 2*d noticed by Yilun Wang)
numDeriv 2011.11-1
- updated maintainer email address.
numDeriv 2010.11-1 (2011-01-20)
- Added warning in the documentation regarding trying to pass arguments
in ... with the same names as numDeriv function arguments.
numDeriv 2010.2-1
- Added more graceful failure in the case of NA returned by a function
(thanks to Adam Kramer).
numDeriv 2009.2-2
- Standardized NEWS format for new function news().
numDeriv 2009.2-1 (2009-02-05)
- argument zero.tol was added to grad, jacobian and genD, and is used to
test if parameters are zero in order to determine if eps should be used
in place of d. Previous tests using == did not work for very small values.
- defaults argument d to grad was 0.0001, but specification made it
appear to be 0.1. Specification was changed to make default clear.
- unnecessary hessian.default argument setting was removed (they are
just passed to genD which duplicated the setting).
- Some documentation links to [stats]numericDeriv mistakenly called
numericalDeriv were fixed.
