Saves keystrokes for computing anomalies.

Arguments

• x: numeric vector
• baseline: logical or numerical vector used for subsetting x before computing the mean
• ...: other arguments passed to mean such as na.rm

Returns

A numeric vector of the same length as x with each value's distance to the mean.

Examples

# Zonal temperature anomaly
library(data.table)
temperature[, .(lon = lon, air.z = Anomaly(air)), by = .(lat, lev)]
