%description
An R interface for libeemd (Luukko, Helske, Räsänen, 2016)
<doi:10.1007/s00180-015-0603-9>, a C library of highly efficient
parallelizable functions for performing the ensemble empirical mode
decomposition (EEMD), its complete variant (CEEMDAN), the regular
empirical mode decomposition (EMD), and bivariate EMD (BEMD). Due to the
possible portability issues CRAN version no longer supports OpenMP, you
can install OpenMP-supported version from GitHub:
