All - Does anyone know if there is a method to calculate a goodness-of-fit statistic for quantile regressions with package quantreg? Specifically, I'm wondering if anyone has implemented the goodness-of-fit process developed by Koenker and Machado (1999) for R? Though I have used package quantreg in the past, I may have overlooked this function, if it is included. Citation: Koenker, R. and J. A. F. Machado. 1999.

Hi all,
For publication purpose, I require to label ggplot figures axes with
sub- or superscript text.
I tried several ways, but never worked so far, to mix character
string, sub- or superscripting on it and even worse, mathematical
symbols.
Let say I want to write the LateX equivalent of \gamma_{fi} in a
ggplot element name, how can I do that?
#dumb example
foo<-data.frame(a=seq(1:100),b=rnorm(100,1,1))
p<-ggplot(data=foo,aes(x=a,y=b))
p<-p + geom_point()
p<-p + scale_x_continuous(name='gamma[fi]')
print(p)
Regards
Ben
