The function reads "GWT" files (i.e. generated using distance. It will read also other more general formats
(as for example .txt files).
Usage
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
skip number of lines
Value
An object of class distance.
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 uniqueregion.id variable.
