[R] Errorbar

[Marc Girondot]

Hi,
I perfectly agree that ggplot package is the perfect solution, but if 
you prefer the old-fashion plot, you can find a plot_errorbar function 
in the package phenology:
plot_errbar(1:100, rnorm(100, 1, 2),
         xlab="axe x", ylab="axe y", bty="n", xlim=c(1,100),
         errbar.x=2, errbar.y=rnorm(100, 1, 0.1))
