A hyperframe is like a data frame, except that its entries can be objects of any kind.
The generic function as.hyperframe converts any suitable kind
of data into a hyperframe.
There are methods for the classes
data.frame, listof, anylist and a default method,
all of which convert data that is like a hyperframe into
a hyperframe object. (The method for the class listof
and anylist converts a list of objects, of
arbitrary type, into a hyperframe with one column.)
These methods do not discard any information.
There are also methods for other classes
(see as.hyperframe.ppx) which extract
the coordinates from a spatial dataset. These methods
do discard some information.
An object of class "hyperframe" created by
hyperframe.
Note that as.hyperframe.default
will convert a character vector to a factor.
It behaves like as.data.frame.
However as.hyperframe.data.frame does not convert strings to
factors; it respects the structure of the data frame x.
The behaviour can be changed using the argument stringsAsFactors.
