subset(x, ...)A Lexis object with selected rows and columns.
an object of class Lexis
additional arguments to be passed to
subset.data.frame. This will normally be some logical
expression selecting a subset of the rows. For details see

The subset method for Lexis objects works exactly as the method
for data frames. So does the "[" method. The special methods are needed in
order to propagate the Lexis-specific attributes.
The method for stacked.Lexis objects also shrinks the set of
levels for lex.Cst and lex.Xst to those actually
occurring in the resulting data frame.
