rmse: Root mean square error

In nobodyinperson/meteoRology: Basic meteorology functions

Description

Calculate the root mean square error of vectors x and y.

Usage

rmse(x, y, na.rm = T)

Arguments

x, y	numerical vectors of same length.
na.rm	Remove NAs prior to calculation? Defaults to TRUE.

Details

sqrt( mean( ( x - y ) ^ 2 ) )

Examples

rmse(1:10,21:30)
# [1] 20
set.seed(42) # We want to produce the same results!
rmse(rnorm(10),rnorm(10))
# [1] 2.108466
