This function calculates the LBI (Label Bias Index) for two self-self hybridization microarrays.
LBI(infile, name.M = "M.norm", ind.array = 1:2, graph = TRUE,
graphout = "FigM1M2")input data file with normalized log-ratio base 2.
character string containing a regular expression contained in the columnames corresponding to the M values.
the indices of arrays to analyze.
logical indicating wether to perform graphics.
