weka.core.converters.CSVLoader

Reads a source that is in comma separated format (the default). One can also change the column separator from comma to tab or another character. Assumes that the first row in the file determines the number of and names of the attributes.

Valid options are:

 -N <range> The range of attributes to force type to be NOMINAL. 'first' and 'last' are accepted as well. Examples: "first-last", "1,4,5-27,50-last" (default: -none-)

 -S <range> The range of attribute to force type to be STRING. 'first' and 'last' are accepted as well. Examples: "first-last", "1,4,5-27,50-last" (default: -none-)

 -D <range> The range of attribute to force type to be DATE. 'first' and 'last' are accepted as well. Examples: "first-last", "1,4,5-27,50-last" (default: -none-)

 -format <date format> The date formatting string to use to parse date values. (default: "yyyy-MM-dd'T'HH:mm:ss")

 -M <str> The string representing a missing value. (default: ?)

 -F <separator> The field separator to be used. '\t' can be used as well. (default: ',')
