Description
The function reads "GWT" files (i.e. generated using distance.
It will read also other more general formats (as for example .txt files).
Usage
1
read.gwt2dist(file, region.id = NULL, skip = 1)
Arguments
file
name of file to be read
region.id
variable that defines the ordering of the observations
skip
number of lines to skip
Details
The first line of a 'GWT' file generally contains some information
(e.g. the name of the shape file, the number of observations),
in which case, skip should be equal to 1.
When the file has a 'GWT' extension,
the number of observations is generally retrived from the first line.
Alternatively, it is fixed to the length
of the unique region.id variable.
Value
An object of class distance
