In EarthSystemDiagnostics/proxysnr: Separate Signal and Noise in Climate Proxy Records

proxysnr 0.2.1

• DiffusionTF(): Bug fix in the error check on correct input vector length.

proxysnr 0.2.0

New function and user-relevant changes

• The function IntegratedSNR() has been added, which takes the job of calculating the signal-to-noise ratio from the integrated signal and noise spectra, so that it delivers the SNR corresponding to varying temporal record resolutions (compared to the SNR at a specific frequency obtained from SeparateSpectra(), which corresponds to a band-pass filtered record). StackCorrelation() internally now uses the new function for an improved code structure.
• Parameter N to StackCorrelation() no longer indicates the maximum number of records but is treated directly as a vector of record numbers; so any call which previously used N = 5 now needs to use N = 1 : 5.
• The rather verbose output of StackCorrelation() has been reduced to the minimum needed - a list of two elements: the frequency axis and the correlation matrix. Output from StackCorrelation() which is piped to the plotting function PlotStackCorrelation() has to be adapted accordingly.

Minor changes

• All code and documentation has been overhauled so that R CMD check passes with zero errors, warnings or notes.
• The location of built vignettes in the source package for documentation on GitHub was changed to reflect recent devtools usage.
• The reference to Muench and Laepple (2018) was updated to reflect the final publication.

proxysnr 0.1.0

• Package version released along with the publication Münch, T. and Laepple, T.: What climate signal is contained in decadal to centennial scale isotope variations from Antarctic ice cores?, Clim. Past, 2018.
