This function performs an one-factorial analysis of variance assessing microtiter plate-dependent bias for a single array
object of class “marrayRaw” or “marrayNorm”
index of array to be tested
anovapin performs a one-factorial ANOVA for objects of class “marrayRaw” or
“marrayNorm”. The predictor variable is the corresponding plate index as stored in the
maPlate slot of
the response variable is the logged fold-change
The null hypothesis is equal
mean(M) of groups of spots derived from the same microtiter plate i.e.
a spot's M does not dependent on the plate of origin.
The model formula used is M ~ (plate.index - 1) (without an intercept term).
The return value is a list of summary statistics of the fitted model as produced by
For example, the squared multiple correlation coefficient R-square equals the proportion
of the variation of
M that can be explained by the variation of plate index (based on the chosen
