FAQ
I'm trying to use the clim.pact
package but I cannot find the
descritions of "map object or "field object". For example,
according to the man page of function "map":

"
Description
Produces maps.

Usage
map(x,y=NULL,col="black",lwd=1,lty=1,sym=TRUE, plot=TRUE,inv.colúLSE)

Arguments x A map object.
...
"

and according to the man page of plotField:

"
Usage
plotField(x,lon=NULL,lat=NULL,tim=NULL,mon=NULL,
col="black",lty=1,lwd=1,what="ano")

Arguments x A field object.
"

retrieve.nc might be a clue, but the
files mentioned in the man page are not included
in the package:

"
Description
Reads a netCDF file and picks out vectors that look like
lngitude, latitude and time. Returns the first 3-D field in the file.
Usage
retrieve.nc(f.name="data/ncep_t2m.nc",..
.../...

Examples
X.1 <- retrieve.nc("data/mpi-gsdio_t2m.nc",
x.rng=c(-60,40),y.rng=c(50,75))
X.2 <- retrieve.nc("data/mpi-gsdio_slp.nc",
x.rng=c(-60,40),y.rng=c(50,75))
"

I've downloaded a sample nc file from
http://www.epic.noaa.gov/java/ncBrowse/
but don't get to use plotField.

Does anyone have any experience using this
package?

Thanks
