## plotField

### Description

Produce 2D plots like maps and Hovmuller diagrams. A poor man's version of Ferret's http://ferret.wrc.noaa.gov/Ferret/ plot function. `plot.field` is a high level command that utilises `mapField` or `grd.box.ts` whenever appropriate.

### Usage

    plotField(x,lon=NULL,lat=NULL,tim=NULL,mon=NULL,val.rng=NULL,
                          col="black",col.coast="grey",lty=1,lwd=1,what="ano",
                          type="l",pch=26,my.col=NULL,add=FALSE,
                          main=NULL,sub=NULL,xlab=NULL,ylab=NULL,
                          xlim=NULL,ylim=NULL)

### Arguments

`x` | A field object.
`lon` | Position for longitude. One of `lon, lat, tim` must be set.
`lat` | Position for latitude.
`tim` | Position for time as time index (1:length(tim).
`mon` | Month to extract.
`val.rng` | Valid range: interval used for colour scale.
`col` | Contour line colour for levels.
`col.coast` | Contour line colour for coast lines.
`lty` | Contour line type.
`lwd` | Contour line width.
`what` | Choose between "ano" - anomaly; "abs" absolute; "cli" climatological.
`type` | same as in plot(), only works for single time series.
`pch` | same as in plot(), only works for single time series.
`my.col` | colour palette (see `link{rgb}`).
`add` | TRUE adds a time series to previous (see `link{grd.box.ts}`).
`main` | Preset main title (see `plot`).
`sub` | subtitle
`xlab` | x label
`ylab` | y label
`xlim` | see `plot`
`ylim` | see `plot`
