|
lhs |
A LoCoH-hullset object |
id |
The name(s) of individuals to export |
k |
The k value of hullsets to export |
r |
The r value of hullsets to export |
a |
The a value of hullsets to export |
s |
The s value of hullsets to export |
hs.names |
The name(s) of saved hullsets to export |
hpp |
Export hull parent points (as a point shapefile). T/F |
hulls |
Export hulls (as a polygon shapefile). T/F |
iso |
Export isopleths (as a polygon shapefile). T/F |
iso.idx |
Numeric vector of the indices of the isopleths that will be exported (acts a filter) |
iso.metric |
Hull sort metric(s) for the isopleths that will be exported (acts a filter). Character vector. |
ellipses |
Export ellipses (as a polygon shapefile). T/F |
dr |
Export directional routes. T/F |
dr.idx |
Numeric vector of the indices of the isopleths that will be exported (acts a filter) |
allpts |
Export all points (as a point shapefile). T/F |
nn |
Export nearest neighbors (as a multipoint shapefile). T/F |
dir |
The directory where the shapefiles will be placed (use "." for the working directory, and "~" for the user directory) |
file.base |
The base of the file name without any extension (the script will append to this) |
file.base.auto |
Whether to automatically generate the file name base from the id, s-value, and k-a-r value. Ignored if |
avl.file |
The name of an existing avl (ArcView legend) file |
status |
Show messages. T/F |
show.time |
Report time for script to complete. T/F |
hm |
The name of hull metric(s) that will be included in the attribute table. Default is 'all'. Applicable only to hulls and hull parent points. Character vector or comma separated string. |
anv |
The name of ancillary variables(s) of the parent point that will be included in the attribute table. Default is NULL. Applicable only to hulls and hull parent points. Character vector or comma separated string. |
hsp |
A list containing one hull scatterplot object with regions saved (i.e., object returned by |
metadata |
Export field descriptions in a meta data file (not yet supported) |
Filenames for the resulting shapefiles are automatically generated, but you can specify the directory with the dir
argument and the
base of the file name with file.base
. The constructed filenames will consist
of a base followed by the name of the hullset and a suffix indicating the type
of feature saved (e.g., '.hulls', '.pts', ".iso", etc. ). If a shapefile already exists with the same name,
a unique filename will be constructed by appending a two-digit numeric extension.
Most of the time, exporting hull parent points (hpp=T
) is the same as exporting all
points (allpts=T
), however in some cases not all points have enough neighbors to make a hull
so they wouldn't be included in exported of hull parent points. Only hull parent points will have the
corresponding hull metrics included in the attribute table.
avl.file
, if passed, is the name of an ArcView 3.x legend file that contains symbology info. If a value is passed,
the script will make a copy of avl.file with the same base name as the shapefile, so that
symbology will automatically created in ArcMap. avl.file
is presumed to be relative
to the working folder.
