Reads the file format that is used by the grid program GRIDCOR (Feixas & Cornejo, 2002).


importGridcor(file, dir = NULL)



filename including path if file is not in current working directory. File can also be a complete URL. The fileformat is .dat.


alternative way to supply the directory where the file is located (default NULL).


a single repgrid object in case one file and a list of repgrid objects in case multiple files are imported.


Note that the GRIDCOR data sets the minimum ratings scale range to 1. The maximum value can differ and is defined in the data file.

Also note that both Gridcor and Gridstat data files do have the same suffix .dat. Make sure not to mix them up.
