[R] how to plot annual values directly

[PIKAL Petr]

Hi

Other option is aggregate or ave, depending on how do you want to plot mean/sum values.

You should think about posting an example of what do you have and what do you want to achieve (at least partly). Without that we are just guessing your real intention.

Cheers
Petr

You could use dplyr:

library(plyr)
ddply(df, .variables = "year", summarise, mean.precip = mean(precip))

Hope this helps
