Get the maximun residual of a BSM at a given iteration

1	max_residual(x, iter = NULL, type = c("normal", "absolute"))

`x`	`bsm` object as returned by `brokenstick` or `optBrokenstick`.
`iter`	the iteration number for which the maximum residual is to be returned (Ri). If `NULL` then `iter` is set to the last iteration in `x`
`type`	To choose in `c('normal', 'absolute')`. The second choice returning the absolute value of the first.

data(exses)
dv <- tdrply(identity, 1:2, no = 100, obj = exses)[[1]]
bsm <- brokenstick(dv) 
max_residual(bsm, iter = 5)

## Not run: 
max_residual(eco.mem(bsm), iter = 5) # error
max_residual(eco.mem(bsm), iter = 4)
