Value

A list with following elements:

properties

A data frame with the class(es), type, mode and storage mode of the object as well as the dim, length and object.size.

attributes.lengths

A named character vector giving all attributes (c.f. “names”, “row.names”, “class”, “dim”, and so forth) along with their length.

extensive.is

A character vector of all the identifier functions. (starting with “is.”) that yield TRUE when used with x as argument.

function.type

When x is a function, results of ftype are added.

An alternative to calling in turn class, typeof, dim, and so on. A call to this function will readily give all this information at once.
