showStructure(x, maxlen = 20, describeAttributes = TRUE, short = NULL, prefix = "", attri = FALSE, ...)
x is a list with more than
maxlen components, only the names are printed.
This may be a vector, in which case the
Kth element is used
at the
Kth level of recursion.
FALSE then only the names of
attributes are printed; the structure of the attributes is not shown.
NULL or logical; this may be used by methods,
to indicate whether to print a shorter description.
It is currently used by
bdFrame and
bdVector methods.
TRUE
if the curent object being described is a list of attributes.
This supports recursive objects, using recursive calls. Each
level of recursion is indented two additional spaces. List components
are shown with
$, slots with
@, and attributes with
&.
