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) [[alternative HTML version deleted]]
Hi What do you mean to plot annual mean/sum directly? You can compute it by aggregate function and add it to your plot, but I am not sure if it is enough direct.

I meant that my dataframe has daily data, but how to plot annual mean/sum directly? Thanks.

Hi
By coincidence I will very soon have to do something similar. So I thought
this would be a practice run
Data is 10 years of daily rainfall data
str(arm)
'data.frame': 3640 obs. of 7 variables:
$ date : Date, format: "1990-01-01" "1990-01-02"
"1990-01-03" "1990-01-04"
...
$ year : int 1990 1990 1990 1990 1990 1990 1990 1990 1990 1990 ...
$ month: int 1 1 1 1 1 1 1 1 1 1 ...
$ day : int 1 2 3 4 5 6 7 8 9 10 ...
$ rain : num 0 19 0 0 0 0 0 8.2 5.6 1 ...
$ doy : num 1 2 3 4 5 6 7 8 9 10 ...
$ ym : Date, format: "1990-01-01" "1990-01-01"
"1990-01-01" "1990-01-01"
...
head(arm)
date year month day rain doy ym
48578 1990-01-01 1990 1 1 0 1 1990-01-01
48579 1990-01-02 1990 1 2 19 2 1990-01-01
48580 1990-01-03 1990 1 3 0 3 1990-01-01
48581 1990-01-04 1990 1 4 0 4 1990-01-01
48582 1990-01-05 1990 1 5 0 5 1990-01-01
48583 1990-01-06 1990 1 6 0 6 1990-01-01
The ym is calculated using ?as.yearmon from the zoo package.
The zoo package may be useful because of its aggregating functions
Need mean daily rain - use whatever aggregation factor/function that you
need
arm.A <- aggregate(rain ~ year, arm, function(x) mean(x[x>0]) )
library(lattice)
xyplot(rain ~ date, arm,
groups = factor(arm$year),
ylim = c(0,60),
avg = arm.A$rain, #
panel = panel.superpose,
panel.groups = function(x, y, type, col,group.number,avg, ...) {
# plot daily values
panel.xyplot(x, y, col = "grey80", type =
"h") # delete if
necessary
# plot average
panel.xyplot(x, avg[group.number], type = "l", col
"black")
}
)

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
