What happens when you follow the directions... i.e. type:
plot.new() #???
Sorry, still fail only an empty grey background diagram displayed.

Hi Stephen,
Please try:
with(ToothGrowth, plot(dose, len))
abline(lm(len ~ dose, data = ToothGrowth))
Cheers,

Hi folks,
Win7 64bit
R 1.12.0
I run following command on R:-
ToothGrowth
attach(ToothGrowth)
plot(dose,len)
matrics=lm(len~dose)
abline(metrics)
Error in int_abline(a = a, b = b, h = h, v = v, untf = untf, ...) :
plot.new has not been called yet
Only a grey diagram is displayed without content
plot(abline(metrics))
Error in int_abline(a = a, b = b, h = h, v = v, untf = untf, ...) :
plot.new has not been called yet
With the same result.
Pls advise what does it mean? How to rectify it? TIA
B.R.
