Subscript a bdFrame

DESCRIPTION:

Extract or replace values from a bdFrame object.

This function requires the bigdata library section to be loaded.

USAGE:

x[j] 
x[j] <- value 
x[[j]] 
x[[j]] <- value 
x[i, j, drop = T] 
x[i, j] <- value 
x$name
x$name <- value

REQUIRED ARGUMENTS:

x
an object inheriting from class "bdFrame".

OPTIONAL ARGUMENTS:

i,j
subscript expressions. See for details of these and other arguments.
drop
logical flag indicating whether dimensions of length 1 are dropped from the return object.
name
a name or quoted string identifying the column to extract or replace.
value
replacement value for the relevant piece of the bdFrame.

DETAILS:

Subscripting a bdFrame is generally similar to subscripting a data frame, with three exceptions:
(1) subscripts ( i and j) may be big data vectors,
(2) matrix subscripts are not currently supported, and
(3) if any columns of the bdFrame have attributes, the attributes are not discarded when rows are subscripted. This is subject to change.
