| Title: | Unified Statistical Modeling of Omics Data |
|---|---|
| Description: | This package unifies access to Statistal Modeling of Omics Data. Across linear modeling engines (lm, lme, lmer, limma, and wilcoxon). Across coding systems (treatment, difference, deviation, etc). Across model formulae (with/without intercept, random effect, interaction or nesting). Across omics platforms (microarray, rnaseq, msproteomics, affinity proteomics, metabolomics). Across projection methods (pca, pls, sma, lda, spls, opls). Across clustering methods (hclust, pam, cmeans). It provides a fast enrichment analysis implementation. And an intuitive contrastogram visualisation to summarize contrast effects in complex designs. |

This is an alternative enrichent analysis implementation.
It is more modular: uses four times .enrichment(VERBOSE)? as backend.
But also four times slower than enrichment, so not recommended.
It is retaind for testing purposes.

A General Linear Model contains:
* An Intercept Coefficient: expressing some form of sample average
* For each numeric variable: a slope coefficient
* For each k-leveled factor: (k-1) Contrast Coefficients.
The interpretation of (intercept and contrast) coefficients depends on the contrast coding function used.
Several contrast coding functions are available in 'stats' and 'codingMatrices'
But their (function and coefficient) namings are a bit confusing and unsystematic.
Instead, the functions below offer an intuitive interface (to the otherwise powerful stats/codingMatrices packages).
The names of these functions reflect the contrast coding used (treatment, backward, sum, or helmert contrasts).
They also reflect the intercept interpretation (either first factor's first level or grand mean).
They all produce intuitive coefficient names (e.g. 't1-t0' rather than just 't1').
They all have unit scaling (a coefficient of 1 means a backward of 1).

subtract_baseline subtracts baseline levels within block, using the
medoid baseline sample if multiple exist.
subtract_pairs also subtracts baseline level within block.
It cannot handle multiple baseline samples, but has instead been optimized
for many blocks
subtract_differences subtracts differences between subsequent levels,
again within block
