biwavelet-package Conduct Univariate and Bivariate Wavelet Analyses
ar1.spectrum Power spectrum of a random red noise process
ar1_ma0_sim Slightly faster 'arima.sim' implementation which assumes AR(1) and 'ma=0'.
arrow Helper function for 'phase.plot' (not exported)
arrow2 This is an alternative helper function that plots arrows. It uses 'text()' to print a character using a default font. This way, it is possible to render different types of arrows.
