The <code>Adler</code> data frame has 97 rows and 3 columns.  
                                                        
The ``experimenters'' were the actual subjects of the study. 
They collected ratings of the apparent successfulness of
people in pictures who were pre-selected for their
average appearance. The experimenters were told prior to collecting 
data that the pictures were either high or low in their 
appearance of success, and were instructed to get good data, 
scientific data, or were given no such instruction. Each 
experimenter collected ratings from 18 randomly assigned
respondents; a few subjects were deleted at random to produce
an unbalanced design.

This package accompanies J. Fox, An R and S-PLUS Companion
        to Applied Regression, Sage, 2002. The package contains mostly
        functions for applied regression, linear models, and
        generalized linear models, with an emphasis on regression
        diagnostics, particularly graphical diagnostic methods. There
        are also some utility functions. With some exceptions, I have
        tried not to duplicate capabilities in the basic distribution
        of R, nor in widely used packages. Where relevant, the
        functions in car are consistent with na.action = na.omit or
        na.exclude.
