Description

Plots time series from field objects, eg from retrieve.nc. Uses a bilinear interpolation scheme (link{interp}) from the akima package.

Usage

grd.box.ts(x,lon,lat,what="abs",greenwich=TRUE,mon=NULL,
                       col="grey10",lwd=1,lty=1,pch=26,add=FALSE,
                       filter=NULL)

Arguments

x A field object.
lon Longitude to plot.
lat Latitude to plot.
what What to draw: "ano"-> anomalies, "cli"-> climatological values, "abs" -> absolute values.
greenwich Maps centre on the Greenwich meridian.
mon Month to extract
col Colour.
lwd Line width
lty Line style.
pch Plot character.
add 'TRUE' adds curve to old plot.
filter If not NULL, this is a vector specifying window weighting argument of same name in link{filter}.

Value
