TANOVA (version 1.0.0)

proj.dir: projection direction

Description

This function is used to estimate the direction that maximize the ANOVA structure of interest.i.e., the direction that contains most useful signal

Usage

"proj"(data,f1,f2,time.course,type,eb=FALSE,df=0,...)
"proj"(data, f1, f2, tp,type=2,trim=0,...)

Arguments

data
a data matrix containing expression values. Row and column represent gene (probe set) and array respectively
f1
a vector containing the levels of a factor in each array
f2
a vector containing the levels of a factor in each array
time.course
the number of time points for which we took sample
tp
a vector containing the sampling time point of each array
type
an indicator of TANOVA test type. 0: classifies genes into gene sets C1,C2, C3,C4 and C5 (constant genes). 1: test for interaction effect. 2: one-way NANOVA test. 3: test main effect f1. 4: test main effect f2.
trim
the percentage to be trimmed from each end of the data
eb
a logical indicator of whether Empirical Bayesian method should be used in the estimation of significance
df
degree of freedom
...
other arguments to be passed on

Value

a
Estimated optimum projection direction (ANOVA direction)
