rline: Resistant line
In bayesball/LearnEDAfunctions: Functions for Learning Exploratory Data Analysis

Fits Tukey's resistant line of form a + b (x - xC).

1	rline(formula, df, iter=1)

`formula`	formula for line of form y ~ x
`df`	data frame
`iter`	number of iterations of algorithm

`a`	value of intercept a
`b`	value of slope b
`xC`	value of xC
`half.slope.ratio`	value of half slope ratio after one iteration
`residual`	vector of residuals
`spoints.x`	vector of summary x coordinates
`spoints.y`	vector of summary y coordinates
