[Rd] quantreg package - predict method for rq objects (PR#2374)

[u9801539@leonard.anu.edu.au]

In help(rq.object), under Methods, it says:
"
The `"rq"' class of objects has methods for the following generic 
     functions:  `coef', `effects' , `formula' , `labels' , 
     `model.frame' , `model.matrix' , `plot' , `predict' , `print' ,
     `print.summary' , `residuals' , `summary'
"
There seems to be no predict method:

> y <- rnorm(500)
> u <- rq(y ~ 1, tau=.75)
Warning message: 
Solution may be nonunique in: rq.fit.br(x, y, tau = tau, ...) 
> predict(u)
Error in predict(u) : no applicable method for "predict"

[I have looked both at the Windows and at the Darwin/X11 versions.]
