Description Usage Arguments Details Value Note Author(s) References See Also Examples

This function generates a sample bivariate data set.

1	sbd(func,min,max,n,Rsq)

`func`	a user supplied function of one variable, y = func(x), near which data is generated.
`min`	min value for the domain of func
`max`	max value for the domain of func
`n`	number of sample points to generate
`Rsq`	coefficient of determination for the data set

If func is NULL then a normal bivariate data set of n samples is generated with correlation coefficient sqrt(Rsq). If func is passed by the user then n sample points are scattered about y=func(x) with variance governed by the Rsq parameter

Returns an n x 2 bivariate data set
