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
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.
