quantRegLines

========================================================

This is an R function to plot multiple quantile regression lines at different levels of tau. It's adapted from the rq helpfile.

```{r  fig.width=7, fig.height=6}

source("./quantRegLines.R")

library(scales)

data(engel)

attach(engel)

taus <- c(.05,.1,.25,.75,.9,.95)

plot(income,foodexp,xlab="Household Income",ylab="Food Expenditure",

     pch=19, col=alpha("black", 0.5))

rq_fit <- rq((foodexp)~(income),tau=taus)

quantRegLines(rq_fit)

```

Or try it with multiple colors

```{r  fig.width=7, fig.height=6}

plot(income,foodexp,xlab="Household Income",ylab="Food Expenditure",

     pch=19, col=alpha("black", 0.5))

quantRegLines(rq_fit, rainbow(6))

legend(4000, 1000, taus, rainbow(6), title="Tau")

```
