kseq: Sequence of Bins or Nearest Neighbours Generation

Description

kseq returns (invisibly) a vector containing numbers of bins $v$ for the histogram and the Parzen window or numbers of nearest neighbours $k$ for the k-nearest neighbour.

Usage

kseq(from = NULL, to = NULL, f = 0.05, ...)

Arguments

from

starting value of the sequence. The default value is NULL.

to

end value of the sequence. The default value is NULL.

f

number specifying the fraction by which the bins or numbers of nearest neighbours should be separated $0.0 \leq f \leq 1.0$. The default value is 0.05.

Examples

## Generate numbers of bins.

n <- 10000

Sturges <- as.integer(1 + log2(n)) ## Minimum v follows the Sturges rule.
Log10 <- as.integer(10 * log10(n)) ## Maximum v follows the Log10 rule.
RootN <- as.integer(2 * n^0.5) ## Maximum v follows the RootN rule.

K <- kseq(from = Sturges, to = Log10, f = 0.05)

K

K <- kseq(from = Sturges, to = RootN, f = 0.03)
