Objects of this class are obtained from class \code{\link{maigesPreRaw}} using function \code{\link{createMaigesRaw}}. } \section{Slots}{ \describe{ \item{\code{Sf}:}{numeric matrix containing the test samples spots intensity values, spots corresponding to rows and data tables (or chips) corresponding to columns.} \item{\code{Sb}:}{numeric matrix containing the test samples local background values, spots corresponding to rows and data tables (or chips) corresponding to columns.} \item{\code{Sdye}:}{character vector with length equal the length of data files (chips), specifying the channel ('ch1' or 'ch2') used to label each test sample in each chip.} \item{\code{Rb}:}{numeric matrix containing the reference samples spots intensity values, spots corresponding to rows and data tables (or chips) corresponding to columns.} \item{\code{Rf}:}{numeric matrix containing the reference samples spots intensity values, spots corresponding to rows and data tables (or chips) corresponding to columns.} \item{\code{Rdye}:}{character vector with length equal the length of data files (chips), specifying the channel ('ch1' or 'ch2') used to label each reference sample in each chip.} \item{\code{Flag}:}{matrix specifying the flags for the spots, as in the matrices above, rows and columns correspond to genes and samples, respectively. Type o value may be numeric or character, depending of the flags used.} \item{\code{BadSpots}:}{logical vector specifying spots that was judged as bad ones. By default this slot is created as a vector of FALSEs with same length as number of spots.} \item{\code{UseSpots}:}{logical matrix indexing the spots to be used for normalisation.} \item{\code{GeneGrps}:}{a logical matrix with rows representing the spots and columns representing different gene groups. Each column give the index of spots in that gene group.} \item{\code{Paths}:}{list containing \code{\link[graph:graphNEL-class]{graphNEL}} objects specifying gene regulatory networks (or pathways). The first object in this list is a char string giving the gene label used to match the genes.} \item{\code{Layout}:}{a list containing the number of rows (\code{gridR}) and columns (\code{gridC}) of grids, the number of rows (\code{spotR}) and columns (\code{spotC}) of spots inside each grid and the total number of spots.} \item{\code{Glabels}:}{data frame giving the gene labels. These labels are generally used during the data analysis.} \item{\code{Slabels}:}{data frame giving the sample labels. These labels are generally used during the data analysis.} \item{\code{Notes}:}{char string that receives any comment about the dataset. The dataset description is stored in this slot.} \item{\code{Date}:}{char string giving the date and hour that the object was created.} \item{\code{V.info}:}{list containg three characters. The first one is a string containing the R version used when the object was created. The second is a char vector with base packages and the last one is another char vector with additional packages and version numbers.} } } \details{ This class of objects defines a real raw object that is used to do the normalisation. Objects of this class are generated from objects of class \code{\link{maigesPreRaw}} using the function \code{\link{createMaigesRaw}}. Here it is possible to do several plots for exploratory analysis using functions from \emph{marray} package. Using the function \code{\link{selSpots}}, you select spots to use in the normalisation method, that is done by the functions \code{\link{normLoc}}, \code{\link{normOLIN}}, \code{\link{normRepLoess}}, \code{\link{normScaleLimma}} and \code{\link{normScaleMarray}}. } \section{Methods}{ \describe{ \item{[}{\code{signature(x = 'maigesRaw')}: subsetting operator for spots on the array or arrays in the batch, ensures that all slots are subset properly.} \item{boxplot}{\code{signature(x = 'maigesRaw')}: boxplot method for \code{\link{maigesRaw}} class. Display boxplots of the slides and print tip groups using package \emph{marray}.} \item{dim}{\code{signature(x = 'maigesRaw', value = 'numeric')}: get the dimensions of the object, numeric vector of length two.} \item{image}{\code{signature(x = 'maigesRaw')}: image method for \code{\link{maigesRaw}} class. Display colour representation of the slides using package \emph{marray}.} \item{plot}{\code{signature(x = 'maigesRaw')}: plot method for \code{\link{maigesRaw}} class.
