R help - Jul 2006 - Quantile Regression Object

Hi,

I load my data set and separate it as folowing:

presu <- read.table("C:/_Ricardo/Paty/qtdata_f.txt", header=TRUE,
sep="\t",
na.strings="NA", dec=".", strip.white=TRUE)
dep<-presu[,3];
exo<-presu[,4:92];

Now, I want to use it using the wls and quantreg packages. How I change the
data classes for mle and rq objects?

Thanks a lot,
Ricardo
