xprnSet and XprnSet create a xprnSet and XprnSet data class structure, respectively. The XprnSet structure contains positive data, which corresponds to measured intensities, abundance levels, etc., whereas the xprnSet structure contains the log of the intensities, log abundance levels, etc. Functions nxprnSet and nXprnSet perform additional checkings on the input data:
The xprnSet class is a wrapper around Bioconductor ExpressionSet class from the Biobase R package. It refers to data of type log ratios, log intensities, log abundance levels, etc.
Statomica is a suite of basic functions and classes that are needed for certain packages. It includes three data class structures; XprnSet, xprnSet and xprnSetPair, and functions to create them from basic data matrices and to manage them. XprnSet, xprnSet and xprnSetPair are wrappers of the data class ExpressionSet in Bioconductors R package Biobase.
xprnSetPair creates a xprnSetPair data class structure from two matrices, numeric, xprnSet or Xprnset data types (inputs x and y have to be of same class). If the input data are XprnSet they are converted to xprnSet by performing log (internally). nxprnSetPair performs some more checkings if input data are numeric or matrix, such as:
The xprnSetPair class is a wrapper around two Bioconductor ExpressionSet class from the Biobase package. The xprnSetPair class contains 2 data sets (matrices) with exactly the same features (in rows) in both data sets.
