[R] thick plot lines

If you include 'type = "l"' (or type = "line") in the qqplot command, you'll
get a line.

Hope this helps,

Subject: [R] thick plot lines

Dear People,

In a qqplot I am doing, I get lines/points that are very thick. I've tried
setting the lwd variable to 0.1, but it doesn't seem to have any effect.
Also, I have set the value of lty to dashed, but I still get dots. The
command looks like

       xlim=c(-theta,theta), ylim=c(-theta,theta), lwd=0.1,
       xlab="Marginal Quartiles", ylab="Empirical Marginal", col="red",

I tried putting


before this, but this doesn't have any effect either.

I'm now wondering if I am doing something wrong. Does qqplot perhaps not
accept these parameters? What should I do to make the lines/points
