unpack.data.frame

Expresses scalar column attributes as column metadata (row values). Column with name <code>meta</code> is created to hold names of attributes, if any. A transposed table (sorted by attribute name) of scalar column attribute values (coerced to character) is bound to the existing data.frame (the attributes themselves are removed from columns). Bind position is controlled by <code>position</code> such that the intersection of new rows and column occurs in the corresponding corner, numbered clockwise from top-left. Resulting column classes are character. It is an error if <code>meta</code> is already in <code>names(x)</code>.

Designs plots in terms of core structure.  See 'example(metaplot)'.
Primary arguments are (unquoted) column names; order and type (numeric or not)
dictate the resulting plot.  Specify any y variables, x variable, any groups variable,
and any conditioning variables to metaplot() to generate density plots, boxplots,
mosaic plots, scatterplots, scatterplot matrices, or conditioned plots. Use multiplot()
to arrange plots in grids. Wherever present, scalar column attributes 'label' and 'guide'
are honored, producing fully annotated plots with minimal effort. Attribute 'guide'
is typically units, but may be encoded() to provide interpretations of categorical
values (see '?encode').  Utility unpack() transforms scalar column attributes to row
values and pack() does the reverse, supporting tool-neutral storage of metadata along
with primary data. The package supports customizable aesthetics such as such as reference
lines, unity lines, smooths, log transformation, and linear fits. The user may choose
between trellis and ggplot output. Compact syntax and integrated metadata promote workflow
scalability.
