TimeTraits: extracting functional traits from biological time-series in R

Abstract

Summary: TimeTraits provides a series of functions to enable the extraction of parameters from time series data using Functional Data Analysis methods. We demonstrate its utility in dissecting the changes in curve shape of a circadian clock bioluminescence marker, following a photoperiod shift in wildtype and phyB Arabidopsis. Availability and Implementation: TimeTraits is available in CRAN: https://cran.r-project.org/web/packages/TimeTraits/readme/README.html
