Create vector of virtual mode

vector.vmode creates a vector of a given vmode and length

Usage

vector.vmode(vmode = "logical", length = 0)
boolean(length = 0)
quad(length = 0)
nibble(length = 0)
byte(length = 0)
ubyte(length = 0)
short(length = 0)
ushort(length = 0)

Arguments

vmode: virtual mode
length: desired length

Details

Function vector.vmode creates the vector in one of the usual storage.modes (see .rammode) but flags them with an additional attribute 'vmode' if necessary. The creators can also be used directly:

`boolean`	1 bit logical without NA
`logical`	2 bit logical with NA
`quad`	2 bit unsigned integer without NA
`nibble`	4 bit unsigned integer without NA
`byte`	8 bit signed integer with NA
`ubyte`	8 bit unsigned integer without NA
`short`	16 bit signed integer with NA
`ushort`	16 bit unsigned integer without NA
`integer`	32 bit signed integer with NA
`single`	32 bit float
`double`	64 bit float
`complex`	2x64 bit float
`raw`	8 bit unsigned char
`character`	character

Value

a vector of the desired vmode initialized with 0
