Dear all,
I am running a code using bootstraps for estimating standard errors but the
mac crashes. When I use small number of bootstraps (100) it works fine but
if I increase that number it crashes.
Thanks in advance

The code, the error and my mac characteristics are the following:
##############code#####################
qr.1<- rq(y~factor(year)+factor(state)+x1+I(x^2)+I(x^3), tau=0.05,
data=data1)
s.qr1.05 <- summary(qr.1, se="boot", R=1000)$coefficient
