[R] Change Variable Labels in Quantile Plot

[Kitty Lee]

Hi Roger,

Maybe I'm missing a clue. Here's an example:

x<-rnorm(50)
x1<-rnorm(50)
y<-x+x1+rnorm(50)


out<-rq(y~x+x1, tau=1:9/10)
plot(summary(out))
plot.out<-plot(summary(out))


#I change the variable names

dimnames(plot.out)<-list(c("intercept", "sex", "inc"))


#Look at the plot
#it's ONE simple scatter plot


plot(plot.out)

#my plot.out looks like this, with my new variable names:

 plot.out

Now I have the right variable names but I can't produce the  right plots. How do I integrate your code?


plot(plot.out, xlab='foo', ylab='bar)


Thanks.
