Hi R users,

I have a dataframe, with daily precipitation data, is it possible to plot
annual mean or annual sum values directly? Thanks for your help.

df
year   month   day   precip       time
2010     1          1        0.5     2010-01-01
2010     1          2        0.8     2010-01-02
2010     1          3        1.0     2010-01-03
2010     1          4        0.9     2010-01-04
...

fig1 = ggplot()+ geom_path(data=df, aes(x=time, y= precip)
show(fig1)
