\name{MmPalateMiRNA-package} \alias{MmPalateMiRNA-package} \alias{MmPalateMiRNA} \docType{package} \title{ R package compendium for the analysis of murine palate two-color miRNA expression data } \description{ R package compendium for the analysis of two-color miRNA expression data, during the period of murine embryonic palate development (gestational days (GD) 12, 13, and 14). Samples were hybridized to Miltenyi Biotech miRXplore Microarrays. The compendium covers a wide range of steps which occur in a typical miRNA microarray data analysis, including pre-processing, normalization, differential expression analysis, clustering, target identification, and gene-set enrichment analysis. } \details{ \tabular{ll}{ Package: \tab MmPalateMiRNA\cr Type: \tab Package\cr Version: \tab 1.0\cr Date: \tab 2011-09-14\cr License: \tab LGPL\cr LazyLoad: \tab yes\cr } The package contains several functions which are helpful during the pre-processing steps of array data, which are specific to \code{\link[limma:RGList-class]{RGList}} objects and, in the case of the \code{\link{fixOutliers}} and \code{\link{fixMVs}} functions, depend on the replicated structure of Miltenyi Biotech miRXplore Microarrays. Additionally, methods are available to produce diagnostic plots for \code{\link[limma:RGList-class]{RGList}} objects and lists of normalized data sets (\code{\link[limma:MAList-class]{MAList}} and / or \code{\link[Biobase:NChannelSet-class]{NChannelSet}} objects), which build on the generic functions in \code{\link[lattice:lattice-package]{lattice}}. Lastly, the main focus of the package is the package vignette "MmPalateMiRNA", which contains an extended example covering the typical steps in an miRNA microarray data analysis. } \author{ Guy Brock, Partha Mukhopadhyay, Vasyl Pihur, Bob Green, M.
