Parabol dataset

Description

Generate a random dataset shaped like a parabol and a gaussian distribution

Usage

data.parabol(
  n = c(500, 100),
  xlim = c(-3, 3),
  center = c(0, 4),
  coeff = 0.5,
  sigma = c(0.5, 0.5),
  levels = NULL,
  graph = FALSE,
  seed = NULL
)

Arguments

`n`	Number of observations in each class.
`xlim`	Minimum and maximum on the x axis.
`center`	Coordinates of the center of the gaussian distribution.
`coeff`	Coefficient of the parabol.
`sigma`	Variance in each class.
`levels`	Name of each class.
`graph`	Whether the generated dataset is plotted. `FALSE` by default, as everywhere else in the package: a generator has to be callable in a loop or a report without piling up graphics devices.
`seed`	A specified seed for random number generation.
