wordfish fitted or predicted object to be shown
the document and feature dimension scores to be extracted as coefficients
additional arguments passed to print
for print method, the object to be printed
max rows of dfm to print
dfm on which prediction should be made
"none" for "raw" scores; "lbg" for LBG (2003)
rescaling; or "mv" for the rescaling proposed by Martin and Vanberg
(2007). (Note to authors: Provide full details here in documentation.)
probability level for confidence interval width
If TRUE, output status messages
number of decimal places to print for print methods
a fitted Wordscores textmodel
additional arguments passed to other functions
for print method, the object to be printed
max rows of dfm to print
for print method, the object to be printed
additional arguments passed to print
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.)
