Newly supported variable type in S3 method:

formula

list

accepts a saved stat output of boxplotdou.

Important changes

Following arguments were removed

at the release on April 2013, because these were actually not working;
color, color.sheer and pars.

Output value format is changed.

Previous output is available as an item of $stat .  This change is to enable replay by previous output by bodplotdou.list(x, ...).

Roll of name.on.axis argument was slightly changed,

name.on.axis=TRUE is now to show lables by abbreviation (a, b, c, ...).   Previsously, the value was to show labels by full name.  To do the same, name.on.axis=NULL or =factor.labels must be specified.  The default action is unchanged, showing full names.  The roll of FALSE is unchanged.  This change is to make the action compatible to factor.labels.

           shading=TRUE, factor.labels=FALSE, name.on.axis=TRUE,
