Hi Rui and Daniel,
Many thanks for your responses. It perfectly works.

Hello,
Right!
I copied from the OP's question without thinking about it.
Corrected would be
bootMedianSE <- function(data, indices){
d <- data[indices, ]
fit <- rq(crp ~ bmi + glucose, tau = 0.5, data = d)
ypred <- predict(fit)
y <- d$crp
median((y - ypred)^2)
}
Sorry,
rui Barradas
