data.gen.spirals(n, cycles = 1, s = 0, do.plot = TRUE)
n
: The data length to be generated.cycles
: The number of cycles of spirals.s
: The level of Gaussian noise, default 0.do.plot
: Logical value. If TRUE (default value), a plot of the generated Spirals is shown.A list of two variables, x and classes.
