News for package kitagawa: CRAN – github

CHANGES IN VERSION 3.1+ (last updated 2025-08-16)

• 3.1.3: added link to psd to satisfy CRAN error

• CI is handled via Github Actions (replaces Travis-CI)

• 3.1.2: Fixed error in vignette engine specification

• 3.1.1: added a ticks.only option to logticks

• 3.1: Added the model of Wang et al (2018; 10.1029/2018WR022793), to the model toolbox and to the ResponseModels toolbox. Thanks to @jkennel for contributing this.

• New test validating Wang model against Hsieh model (they are equivalent when specific leakage is zero). Thanks to @jkennel for contributing this.

• Previous build on CRAN broke because sapa/ifultools were removed; hence, the specifics of cross_spectrum have changed. The code now uses new functionality from the CRAN package. (sapa/ifultools were unreliablely maintained for a while.) One benefit is this new approach allows for adaptive refinement of the (sine-multitaper) cross spectrum rather than uniform tapering across all frequencies. But, one unfortunate consequence is that any codes/scripts using the Welch option (i.e., k=NULL) will break.

CHANGES IN VERSION 2.3 (2019-09-18)

• Fixes a sign error in the Liu solution. Thanks to @jkennel for catching this.

• Removed the need for pandoc-citeproc in Tohoku vignette because of a presently unfixed bug.

CHANGES IN VERSION 2.2-2 (2018-09-14)

• NA values stop execution of cross_spectrum; and, added tests.

• NEW FUNCTION: logsmoo which can be used to smooth hdr signals in log-space

• UPDATED: Tohoku cross-spectrum vignette

• Added DOIs for references

CHANGES IN VERSION 2.2-1 (2018-01-20)

• Added optional switch to cross_spectrum to switch from multitaper to Welch overlapping estimation

CHANGES IN VERSION 2.2-0 (2017-07-11)

• Tohoku cross-spectrum vignette

• Function for cross-spectrum computation

• Includes Windows CI via AppVeyor

• unit-testing framework (testthat, CRAN), with some tests

CHANGES IN VERSION 2.1-1 (2015-02-10)

• Mostly a maintenance release.

• Travis-CI is now used to track builds; see also the github page.

CHANGES IN VERSION 2.1-0 (2013-10-03)

• New capability to model open well response: open_well_response

• well_response now returns complex frequency response only, rather than returnin amplitude and phase as separate vectors.

• Substantial documentation improvements (and shuffling around).

• Response functions now add attributes and class to output: 'wrsp' and 'owrsp' for sealed and open well response, respectively.

• New methods for 'wrsp' and 'owrsp', including plot.wrsp, for example.

• kitplot is simply a link to plot.wrsp

• Changed variable names in well_response and added defaults in case some are missing.

• Added a vignette highlighting model differences.

• New utility function .in0to1 to test for existence between zero to one; this is useful to check if a parameter is valid (e.g. Skemptons ratio).

• New utility constants to access stored physical constants.

CHANGES IN VERSION 1.1-1 (2013-03-12)

• Removed empty .Last.lib function.

• Added missing closures in 'NEWS.Rd'.

CHANGES IN VERSION 1.1-0 (2013-03-11)

• Added .onAttach message into 'zzz.R' file.

• NEWS is now in Rd format in the inst/ directory.

CHANGES IN VERSION 1.0-1 (2012-10-25)

• This marks the first release to CRAN.

• added a demo

• bug fix: when given a single frequency (omega), the calculation failed

• documentation improved

CHANGES IN VERSION 1.0-0 (2012-09-27)

• First version, checks ok.

• Documentation complete, thanks to roxygen2 (CRAN).
