You can define a grid using Microsoft Excel and by saving it as a .xlsx file. The .xlsx file has to be in a specified fixed format (see section Details).


importExcel(file, dir = NULL, sheetIndex = 1, min = NULL, max = NULL)



A vector of filenames including the full path if file is not in current working directory. The file suffix has to be .xlsx (used since Excel 2007).


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


The number of the Excel sheet that contains the grid data.


Optional argument (numeric, default NULL) for minimum rating value in grid.


Optional argument (numeric, default NULL) for maximum rating value in grid.


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


Excel file structure: The first row contains the minimum of the rating scale, the names of the elements and the maximum of the rating scale. Below every row contains the left construct pole, the ratings and the right construct pole.

left pole 11534right pole 1
left pole 23113right pole 2
left pole 34251right pole 3

Note that the maximum and minimum value has to be defined using the min and max arguments if no values are supplied at the beginning and end of the first row. Otherwise the scaling range is inferred from the available data and a warning is issued as the range may be erroneous. This may effect other functions that depend on knowing the correct range and it is thus strongly recommended to set the scale range correctly.
