legend() with option adj=1

Is there a simpler way then the solution to the one that was posted here?  I'm 
not very proficient with legend, and I don't understand this solution.   All 
I have is two or more lines on one plot that I want to put a legend on and I 
can't figure out how to do it from the examples.  Can you give a very simple 
example? It does not have to be fancy!!  I have never worked with a package 
where the legend was not automatic.

Hi there,

I want to justify to right the text of my legend. Consider this short
reproducable example.

x <- 1:5
y1 <- 1/x
y2 <- 2/x
plot(rep(x,2),c(y1,y2),type="n",xlab="x",ylab="y")
lines(x,y1)
lines(x,y2,lty=2)
legend(5,2,c("1,000","1,000,000"),lty=1:2,xjust=1,yjust=1)
legend(5,1.5,c("1,000","1,000,000"),lty=1:2,xjust=1,yjust=1,adj=1)

Now, I would like to right-justify the text of the legend. As you can see,
the option adj=1 does not give satisfactory results.

Is this a bug or is there an easy way that I'm missing?

Thanks,
Jerome

Works, e.g., with the following little trick:

  x <- 1:5
  y1 <- 1/x
  y2 <- 2/x
  plot(rep(x,2),c(y1,y2),type="n",xlab="x",ylab="y")
  lines(x,y1)
  lines(x,y2,lty=2)
  temp <- legend(5, 2, legend = c(" ", " "),
    text.width = strwidth("1,000,000"), lty = 1:2, xjust = 1, yjust = 1)
  text(temp$rect$left + temp$rect$w, temp$text$y,
     c("1,000", "1,000,000"), pos=2)

See ?legend for details, in particular the returned value.
