integrOmics: an R package to unravel relationships between two omics datasets.
TL;DR: IntegrOmics efficiently performs integrative analyses of two types of ‘omics’ variables that are measured on the same samples and includes a regularized version of canonical correlation analysis and a sparse version of partial least squares regression that includes simultaneous variable selection in both datasets.
Journal ArticleDOI
CCA: An R Package to Extend Canonical Correlation Analysis
TL;DR: An R package, CCA, is implemented, freely available from the Comprehensive R Archive Network, to develop numerical and graphical outputs and to enable the user to handle missing values.
Journal ArticleDOI
Visualising associations between paired 'omics' data sets.
TL;DR: This paper proposes to revisit few graphical outputs to better understand the relationships between two ‘omics’ data and to better visualise the correlation structure between the different biological entities and demonstrates the usefulness of such graphical outputs on several biological data sets.

TL;DR: The PhyloChip as discussed by the authors used 16S rRNA gene microarray, which targets 8741 bacterial and archaeal taxa, to interrogate microbial communities inhabiting densely vegetated and bare fell-field soils along a latitudinal gradient ranging from 51 degrees S (Falkland Islands) to 72 degrees S(Coal Nunatak).

TL;DR: The results suggest that dietary FAs represent—even under low fat intake conditions—a beneficial strategy to reduce hepatic steatosis, and highlight its importance in regulating hepatic FA content and composition.
