Such things are very easy with the ggplot2 package
install.packages("ggplot2")
library(ggplot2)
Dataset <- data.frame(A = c(10,20,40,80), B = c(30,40,100,200))
ggplot(data = Dataset, aes(x = A, y = B)) + geom_point() +
geom_smooth(method = "lm")
More info and example on the ggplot2 website: http://had.co.nz/ggplot2/
Best regards,
Thierry

To call in the statistician after the experiment is done may be no more
than asking him to perform a post-mortem examination: he may be able to
say what the experiment died of.
~ Sir Ronald Aylmer Fisher
The plural of anecdote is not data.
~ Roger Brinner
The combination of some data and an aching desire for an answer does not
ensure that a reasonable answer can be extracted from a given body of
data.

> x<-c(10,20,40,80)
> y<-c(30,40,100,200)
> plot(x,y,type="p")
> lines(lm(x~y),col="red",lwd=1.5)

> I got only plot without linear line.
> Many thanks ahead for your advice!
