spc_vector: Create Vector of Spectrum Elements (zipfR)
In zipfR: Statistical Models for Word Frequency Distributions

Description Usage Arguments Details Value See Also Examples

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).

1	spc.vector(obj, m.min=1, m.max=15, all=FALSE)

`obj`	an object of class `spc`, representing an observed or expected frequency spectrum
`m.min, m.max`	determine the range of frequency classes to be returned (defaulting to 1 ... 15)
`all`	if `TRUE`, a vector containing the entire frequency spectrum is returned, i.e. `m.max` is set to `max(obj$m)`. Note that the value of `m.min` can still be overridden manually to return only part of the spectrum.

spc.vector(obj, a, b) is fully equivalent to Vm(obj, a:b) (and is implemented in this way).

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).

Vm.spc for an alternative way of extracting spectrum vectors from a .spc object, and N.spc, V.spc, VV.spc, VVm.spc for extracting related information

## 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)
