[R] qqline function doesn't plot

[john seers (IFR)]

Hi

qqline does not do the plot. It adds a line to an existing plot.

So you have to do something else first, like:

qqnorm(x)
qqline(x)

JS

Subject: [R] qqline function doesn't plot


I have a data vector x.  When I try 

qqline(x)

I get the following error:

Error in int_abline(a = a, b = b, h = h, v = v, untf = untf, ...) : 
  plot.new has not been called yet

And a blank plot appears.

Can anybody help?  What am I doing wrong?

Thanks,
Scotty
