climanomaly

Visualise anomalies between two lines (e.g. a time series and a climatology)

CLIMANOMALY plots two lines (y vs. x and y vs. ref) and visualises positive and negative anomalies by shading the area between both lines in two different colors. This is useful for visualising anomalies of a time series relative to a climatology.
The function is based on Chad A. Greene's anomaly function, which plots anomalies relative to a constant baseline or two threshold baselines (positive anomaly above upper threshold, negative anomaly below lower threshold). These options are available in 'climanomaly' as well.
