Jean, how would you modify your function to grab all the selected and not just
the first?
Thank you so much!

I wrote a little function called first() to help with situations like
this. It returns a 1 every time an element of a vector is different from
the previous element, and a 0 otherwise.
first <- function(x) {
L <- length(x)
c(1, 1-(x[-1]==x[-L]))
}
sd <- 1
residuals <- c(1, 2.1, 3, 4
