R help - Jul 2009 - Selecting Bootstrap Method for Quantile Regression

The help page and vignette for summary.rq(quantreg) mention that there are
three different bootstrap methods available for the se="bootstrap"
argument,
but I can't figure out how to select a particular method. For example, if I
want to use the "xy-pair bootstrap" how do I indicate this in
summary.rq?

Hi Tom,

The general approach is documented under summary.rq (sub se option 5).
Shorter route is boot.rq, where examples are given.

## ?boot.rq
y <- rnorm(50)
x <- matrix(rnorm(100),50)
fit <- rq(y~x,tau = .4)
summary(fit,se = "boot", bsmethod= "xy")

Regards, Mark.
