rmatCalc

Two biological conditions dataset matrix

fvect

Number of genes or probes in the dataset

Number of samples in the first biological condition

Number of samples in the second biological condition

This is an internal function for using a C code to calculate a
vector form of the matrix of fold changes using pairwise comparison of data samples.

A fold change rank based method is presented to search for genes with changing
expression and to detect recurrent chromosomal copy number aberrations. This
method may be useful for high-throughput biological data (micro-array, sequencing, ...).
Probabilities are associated with genes or probes in the data set and there is no
problem of multiple tests when using this method. For array-based comparative genomic
hybridization data, segmentation results are obtained by merging the significant
probes detected.
