Dear Users,
I loaded my dataset as following:
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];
When I try:
rq(dep ~ exo, ...) or mle.stepwise(dep ~ exo, ...)
I got the same error:
> rq(dep ~ exo)
Error in model.frame(formula, rownames, variables, varnames, extras,
extranames, :
invalid variable type for 'exo'
Any hint in how to fix it? I think this is due my data format.
Thanks,

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
