Convert big data objects

DESCRIPTION:

Convert between bdFrame and data.frame objects.

This function requires the bigdata library section to be loaded.

USAGE:

as.bdFrame(x)
is.bdFrame(x)

REQUIRED ARGUMENTS:

x
A data.frame.

VALUE:

Returns a bdFrame object.

DETAILS:

If as.bdFrame is given a bdFrame, then it is simply returned; otherwise, it is converted.

Some data.frame elements are not supported by bdFrame. Unsupported elements include row names, attributes, and so on. Converting from a data.frame to a bdFrame and back drops these elements.
