[R] An empty grey diagram

[Stephen Liu]

Hi Josh,


> with(ToothGrowth, plot(dose, len))
> abline(lm(len ~ dose, data = ToothGrowth))

ToothGrowth
abline(lm(len ~ dose, data = ToothGrowth))
Error in int_abline(a = a, b = b, h = h, v = v, untf = untf, ...) : 
  plot.new has not been called yet

ToothGrowth
attach(ToothGrowth)
abline(lm(len ~ dose, data = ToothGrowth))
Error in int_abline(a = a, b = b, h = h, v = v, untf = untf, ...) : 
  plot.new has not been called yet


Sorry, still fail only an empty grey background diagram displayed.


B.R.

Hi Stephen,

Please try:

with(ToothGrowth, plot(dose, len))
abline(lm(len ~ dose, data = ToothGrowth))


Cheers,

Josh
