R Documentation

Generate numbers from a Halton Sequence.

Description

For efficiency, this function can generate points along a random start Halton Sequence for a predefined Halton.

Usage

cppBASpts(
  n = 10L,
  seeds = as.integer(c()),
  bases = as.numeric(c()),
  verbose = FALSE
)

Arguments

`n`	Number of points required.
`seeds`	Random starting point in each dimension.
`bases`	Co-prime base for the Halton Sequence.
`verbose`	A boolean indicating whether informational messages are to be issued.

Value

Matrix with the columns, order of points, x in [0,1) and y in [0,1)

Author(s)

This function was first written in R by Blair Robertson, subsequently it was re-written in C/C++ by Phil Davies.

Examples

# First 10 points in the Halton Sequence for base 2,3
spbal::cppBASpts(n = 10)
# First 10 points in the Halton Sequence for base 2,3 with
# starting point at the 15th and 22nd index.
spbal::cppBASpts(n = 10, seeds = c(14, 21))
