EOF.mvcombR Documentation

Multivariate Empirical Orthogonal Functions (EOFs).

Description

Computes EOFs (a type of principal component analysis) for an mvcomb object which is the combination of two fields of different variables and output of the mvcombine function.

Usage

## S3 method for class 'mvcomb'
EOF(
  X,
  Y = NULL,
  it = NULL,
  is = NULL,
  n = 20,
  lon = NULL,
  lat = NULL,
  geoweighting = FALSE,
  verbose = FALSE,
  ...
)

Arguments

X

An mvcomb object or field object

Y

A field object. If two field objects X and Y are provided, mvcombine is applied to combine the two.

it

A list or data.frame providing time index, e.g. a range of years like c(1979,2010), a season ('djf'), or a month ('dec' or 'december').

is

A list or data.frame providing space index, e.g. a list of longitude and latitude range like list(lon=c(0,60), lat=c(35,60)).

n

Number of EOFs.

lon

set longitude range - see t2m.NCEP

lat

set latitude range.

verbose

If TRUE print diagnostics
