Subject: ISwR Plotting Issue
I'm trying to replicate the linear regression plot on pages 112-113 in
Peter Dalgaard's "Introductory Statistics with R" and getting the error that
"plot.new has not been called yet."
A Web search on that error offered suggestions to run plot.new() or x11(),
but all those do is put up an empty plotting window. My code, and R's
responses, follow:
> library(ISwR)
Attaching package: ?ISwR?
The following object is masked from ?package:survival?:
lung
> attach(thuesen)
> plot(blood.glucose,short.velocity)
> abline(lm(short.velocity ~ blood.glucose))
Error in int_abline(a = a, b = b, h = h, v = v, untf = untf, ...) :
plot.new has not been called yet
What have I missed here?
