Create Vector of Spectrum Elements (zipfR)
Description
spc.vector
returns a selected range of elements from a
frequency spectrum as a plain numeric vector (which may contain
entries with V_m = 0
, unlike the spc
object
itself).
Usage
spc.vector(obj, m.min=1, m.max=15, all=FALSE)
Arguments
obj |
an object of class |
m.min , m.max |
determine the range of frequency classes to be returned (defaulting to 1 ... 15) |
all |
if |
Details
spc.vector(obj, a, b)
is fully equivalent to Vm(obj,
a:b)
(and is implemented in this way).
Value
A numeric vector with the selected elements of the frequency spectrum.
In this vector, empty frequency classes (V_m = 0
) are
represented by 0 entries (unlike the spc
object, which omits
all empty classes).

Examples
## Brown Noun spectrum
data(BrownNoun.spc)
## by default, extract first 15 elements
spc.vector(BrownNoun.spc)
## first five elements
spc.vector(BrownNoun.spc,1,5)
## just frequencies of spc elements 4 and 5
spc.vector(BrownNoun.spc,4,5)
## same as
Vm(BrownNoun.spc,4:5)
