level

probability level for confidence interval width

verbose

If TRUE, output status messages

digits

Value

The predict method for a wordscores fitted object returns a data.frame whose rows are the documents fitted and whose columns contain the scored textvalues, with the number of columns depending on the options called (for instance, how many rescaled scores, and whether standard errors were requested.) (Note: We may very well change this soon so that it is a list similar to other existing fitted objects.)
