abs2ratio: Convert log-values to log-ratios

In timecourse: Statistical Analysis for Developmental Microarray Time Course Data

Description

For a single gene, computes the log ratios between time courses from two paired biological conditions.

Usage

abs2ratio(x, mn, k, c.grp, reference)

Arguments

x	a numeric vector giving the log-values of a gene with two paired biological conditions, sorted in ascending order by biological condition, replicate, and time groups.
mn	a numeric matrix giving the sample sizes for the two biological conditions.
k	a positive integer giving the number of time points.
c.grp	an numeric or character vector with length equals to that of x, giving the biological condition group for each element of x.
reference	a numeric value or character assigning the reference biological condition.

Details

This function is for internal use only and is not to be called by the user.

Value

a numeric vector containing log-ratios between two paired biological conditions.
