%description
Performs the O2PLS data integration method for two datasets, yielding
joint and data-specific parts for each dataset. The algorithm
automatically switches to a memory-efficient approach to fit O2PLS to high
dimensional data. It provides a rigorous and a faster alternative
cross-validation method to select the number of components, as well as
functions to report proportions of explained variation and to construct
plots of the results. See the software article by el Bouhaddani et al
(2018) <doi:10.1186/s12859-018-2371-3>, and Trygg and Wold (2003)
<doi:10.1002/cem.775>. It also performs Sparse Group (Penalized) O2PLS,
see Gu et al (2020) <doi:10.1186/s12859-021-03958-3> and cross-validation
for the degree of sparsity.
