## Principal Oscillating Patterns

### Description

After von Storch & Zwiers (1999), Statistical Analysis in Climate Research, p. 338.

### Usage

    POP(x,plot=TRUE,main="POP analysis",sub="",test=FALSE,i.eofs=1:8,LINPACK=TRUE, mode = 1)
    plotPOP(pop,mode = 1, main = "POP analysis", sub = "")

### Arguments

`x` | A field or an eof object.
`plot` | Flag: plot the diagnostics.
`test` | Flag: test by reconstructing one series (leading EOF or a grid-box series).
`i.eofs` | Which EOFs to include (only when the input is given as eof objects).
`LINPACK` | 'TRUE': svd; 'FALSE':La.svd
`main` | main title (see `link{plot}`).
`sub` | subtitle (see `link{plot}`).
`mode` | POP mode to display
`pop` | a POP object.

### Value

A POP object: an `link{eigen}` object with additional variables. maps (map of the absolute of POP patterns), pop.Im (the imaginary POP pattern), pop.Re(the real POP pattern), lon (longitude coordinates), and lat (latitude coordinates).

    ## Not run:
    data(DNMI.t2m)
