News for package kitagawa: CRAN – github – Travis-CI – AppVeyor-CI

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.

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.

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

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.
