You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: anova1.m
    path of file: ./repos/matStats/matStats/tabstats
    
    the code of the file until where you have to start completion: function anova1(this, factor, varargin)
%ANOVA1 One-way analysis of variance
%
%   anova1(DATA, FACTOR)
%   At least DATA or FACTOR should be a data table with one column, the
%   other argument, must be a data table or a column vector the same size.

    
function anova1(this, factor, varargin)
%ANOVA1 One-way analysis of variance
%
%   anova1(DATA, FACTOR)
%   At least DATA or FACTOR should be a data table with one column, the
%   other argument, must be a data table or a column vector the same size.
%   The functions formats inputs, and call the "anova1" function in the
%   statistics toolbox.
%
%   anova1(..., NAME, VALUE)
%   Specifies additional parameters that will be passed to the boxplot
%   function.
