grid.maker: grid maker

In floswald/gridR: gridR: create different scalings of uniformly spaced grids.

Description

produce differently scaled one-dimensional grids

Usage

  grid.maker(bounds, num.points, spacing = "log.g",
    plotit = FALSE, ...)

Arguments

bounds	numeric vector of length 2: bounds of interval
num.points	number of points desired
spacing	character vector indicating the desired spacing rule. Currently one of expo, expo2, hyp.sine, log.grid, gumbel.grid, lognorm.grid or beta.grid
plotit	boolean TRUE if want a plot of result
...	additional arguments needed for grid.makers using distributions

Value

numeric vector of class "gridR" with attribute "spacing"

Examples

grid.maker(bounds=c(-1,5),num.points=10,spacing="log.g",plotit=FALSE)
grid.maker(bounds=c(-1,5),num.points=10,spacing="log.g",plotit=TRUE)
grid.maker(bounds=c(-1,5),num.points=10,spacing="log.g2",plotit=TRUE)
grid.maker(bounds=c(-1,5),num.points=10,spacing="log.g2",plotit=FALSE)
grid.maker(bounds=c(-1,5),num.points=10,spacing="hyp.sine",plotit=FALSE)
grid.maker(bounds=c(-10,10),num.points=20,spacing="hyp.sine",plotit=TRUE)
grid.maker(bounds=c(-1,5),num.points=10,spacing="exp.grid",plotit=TRUE)
grid.maker(bounds=c(-1,5),num.points=10,spacing="exp.grid",plotit=FALSE)
grid.maker(bounds=c(1,5),num.points=10,spacing="lognorm.grid",plotit=TRUE,meanlog=3,sdlog=0.5)
grid.maker(bounds=c(-1,5),num.points=10,spacing="lognorm.grid",plotit=FALSE,meanlog=3,sdlog=0.5)
grid.maker(bounds=c(-1,5),num.points=10,spacing="gumbel.grid",plotit=TRUE,loc=1,scale=1.1)
grid.maker(bounds=c(-1,5),num.points=10,spacing="gumbel.grid",plotit=FALSE,loc=1,scale=1.1)
grid.maker(bounds=c(-1,50),num.points=10,spacing="gumbel.grid",plotit=TRUE,loc=1,scale=10)
grid.maker(bounds=c(-1,50),num.points=10,spacing="gumbel.grid",plotit=TRUE,loc=10,scale=10)
grid.maker(bounds=c(-1,5),num.points=10,spacing="beta.grid",plotit=TRUE,shape1=2,shape2=5,ncp=0)
grid.maker(bounds=c(-10,5),num.points=20,spacing="beta.grid",plotit=TRUE,shape1=0.5,shape2=0.5,ncp=0)
grid.maker(bounds=c(-10,5),num.points=20,spacing="beta.grid",plotit=TRUE,shape1=0.5,shape2=1,ncp=0)
grid.maker(bounds=c(-10,5),num.points=20,spacing="beta.grid",plotit=TRUE,shape1=0.5,shape2=1,ncp=2)
grid.maker(bounds=c(-1,5),num.points=10,spacing="beta.grid",plotit=FALSE,shape1=2,shape2=5,ncp=1)
