Big Data Logical Vectors

DESCRIPTION:

Create or test for big data objects representing logical vectors.

This function requires the bigdata library section to be loaded.

USAGE:

bdLogical(length = 0)
as.bdLogical(x)
is.bdLogical(x)

REQUIRED ARGUMENTS:

length
integer giving the length of the returned object.
x
A vector, bdVector, or single-column bdFrame.

Any S-PLUS object for is.bdLogical.

VALUE:

bdLogical and as.bdLogical return an object of class bdLogical, the big data analog of a logical vector.

is.bdLogical returns TRUE if x inherits from bdLogical, and FALSE otherwise.

EXAMPLES:

bdLogical(5)

as.bdLogical( c(T, T, F, F, NA) )

bd.fuel <- as.bdFrame(fuel.frame)
is.bdFactor(bd.fuel$Weight > 2000)
