read.coastline.shapefile: Read a Coastline File in Shapefile Format
Description
Read coastline data stored in the shapefile format [1].
Usage
read.coastline.shapefile(file, lonlim = c(-180, 180), latlim = c(-90, 90), debug = getOption("oceDebug"), monitor = FALSE, processingLog)
Arguments
file
name of file containing coastline data.
lonlim
as latlim, but a signed longitude.
latlim
range of (signed) latitudes, used only for shapefiles.
Regions that do not intersect this range are skipped.
debug
set to TRUE to print information about the header, etc.
monitor
Logical indicating whether to print an indication of progress through
the file.
processingLog
if provided, the action item to be stored in the log.
(Typically only provided for internal calls; the default that it provides is
better for normal calls by a user.)
A hack for depth contours
The following demonstrates that this
code is getting close to working with depth contours. This should be
handled more internally, and a new object for depth contours should be
constructed, of which coastlines could be a subset.See Also
