ID32.dat

<p>The data set <code>ID32.dat</code> contains a paleoclimate 
(pollen percentages) time series spanning a time interval between 73,000 
and 15,000 years before present (BP), thus covering the last glacial period 
(LGP). This data set come from a global pollen and charcoal database 
(Sánchez Goñi et al., 2017) developed in the framework of the INQUA 
International Focus Group ACER (Abrupt Climate Changes and Environmental 
Responses). The time series come from the site MD95-2039 and contains 141 
elements (Roucoux et al., 2005; Sánchez Goñi et al., 2017).</p>

Estimate the correlation between two irregular time series that are not necessarily sampled on identical time points. This program is also applicable to the situation of two evenly spaced time series that are not on the same time grid. 'BINCOR' is based on a novel estimation approach proposed by Mudelsee (2010, 2014) to estimate the correlation between two climate time series with different timescales. The idea is that autocorrelation (AR1 process) allows to correlate values obtained on different time points. 'BINCOR' contains four functions: bin_cor() (the main function to build the binned time series), plot_ts() (to plot and compare the irregular and binned time series, cor_ts() (to estimate the correlation between the binned time series) and ccf_ts() (to estimate the cross-correlation between the binned time series). A description of the method and package is provided in Polanco-Martínez et al. (2019), <doi:10.32614/RJ-2019-035>.
