proj.dir: projection direction
In TANOVA: Time Course Analysis of Variance for Microarray

Description Usage Arguments Value Author(s) See Also

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

## S3 method for class 'dir'
proj(data,f1,f2,time.course,type,eb=FALSE,df=0,...)
## S3 method for class 'dir2'
proj(data, f1, f2, tp,type=2,trim=0,...)

`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
