%description
Estimates and plots (as a single plot and as a heat map) the rolling
window correlation coefficients between two time series and computes their
statistical significance, which is carried out through a non-parametric
computing-intensive method. This method addresses the effects due to the
multiple testing (inflation of the Type I error) when the statistical
significance is estimated for the rolling window correlation coefficients.
The method is based on Monte Carlo simulations by permuting one of the
variables (e.g., the dependent) under analysis and keeping fixed the other
variable (e.g., the independent). We improve the computational efficiency
of this method to reduce the computation time through parallel computing.
The 'NonParRolCor' package also provides examples with synthetic and
real-life environmental time series to exemplify its use. Methods derived
from R. Telford (2013) <https://quantpalaeo.wordpress.com/2013/01/04/> and
