lmCSmat: Cosinor

In DiscoRhythm: Interactive Workflow for Discovering Rhythmicity in Biological Data

Description

Fixed period cosinor ("harmonic regression") on each row of a matrix

Usage

lmCSmat(x, zts, per = 24)

Arguments

x	- numeric data matrix
zts	- numeric vector of length ncol(data) representing time points for each data column
per	- period of oscillations (default=24)

Details

Fits a cosinor model to each row of a matrix.

Value

data frame with the following estimated statistics:

• acrophase - acrophases

• amplitude - amplitudes

• Rsq - r-squared values

• pvalue - p-values

• mesor - intercept coefficient

• sincoef - sine coefficient

• coscoef - cosine coefficient
