Hi, Here are my data:> duser files date 1 alice 18 2013-09-15 2 bob 5 2013-09-15 3 carol 21 2013-09-15 4 alice 22 2013-09-08 5 bob 9 2013-09-08 6 carol 14 2013-09-08 7 alice 26 2013-09-01 8 bob 3 2013-09-01 9 carol 22 2013-09-01 I would like to plot the number of files against date for all users, so I have: library(ggplot2) people <- c("alice","bob","carol") user <- c(rep(people,3)) files <- c(18,5,21,22,9,14,26,3,22) date <- c(rep("2013-09-15",3),rep("2013-09-08",3),rep("2013-09-01",3)) d <- data.frame(user=user,files=files,date=date) p <- ggplot() p <- p + geom_line(data=d,aes(x=date,y=files,group=user,colour=user)) I would now like to add a line to show the total number of files as a function of date. I tried p <- p + geom_line(data=d,aes(x=date,y=sum(files),group=date),colour='black') I don't get a black line, but the plot is scaled such that I can see that sum(file) for all values of 'file', rather than those for each date, is being used. I would like to know how to do this correctly, but I would rather be able to work it out for myself. However, if I decide, say, that I don't know exactly what the 'group' argument does, how do I find it out? ?geom_line doesn't have it, although the examples there use it. ?ggplot doesn't mention it. ?group gives me stuff about formatting text arguments. ??group only leads me to ?ggplot2::add_group, which also does not seem to help. Am I at fault for trying to learn R in an ad hoc manner, to which the documentation of R does not lend itself, or am I missing something?

Hi Not extremely clear what do you want to plot. Do you want to add a line which marks total number of files each day regardless of user? Or a total number of files regardless of date coloured by user? In each case you shall search functions geom_hline or geom_abline http://stackoverflow.com/questions/13254441/add-a-horizontal-line-to-plot-and-legend-in-ggplot2 ggplot is rather complicated but very flexible Petr> -----Original Message----- > From: R-help [mailto:r-help-bounces at r-project.org] On Behalf Of Loris > Bennett > Sent: Monday, March 09, 2015 2:56 PM > To: r-help at stat.math.ethz.ch > Subject: [R] Add sum line to plot of multiple x values > > Hi, > > Here are my data: > > > d > user files date > 1 alice 18 2013-09-15 > 2 bob 5 2013-09-15 > 3 carol 21 2013-09-15 > 4 alice 22 2013-09-08 > 5 bob 9 2013-09-08 > 6 carol 14 2013-09-08 > 7 alice 26 2013-09-01 > 8 bob 3 2013-09-01 > 9 carol 22 2013-09-01 > > I would like to plot the number of files against date for all users, so > I have: > > library(ggplot2) > > people <- c("alice","bob","carol") > user <- c(rep(people,3)) > files <- c(18,5,21,22,9,14,26,3,22) > date <- c(rep("2013-09-15",3),rep("2013-09-08",3),rep("2013-09- > 01",3)) > d <- data.frame(user=user,files=files,date=date) > > p <- ggplot() > p <- p + geom_line(data=d,aes(x=date,y=files,group=user,colour=user)) > > I would now like to add a line to show the total number of files as a > function of date.

For each user: the number of files for each date (my code does this) 2. The sum of files of all users for each date (this is what I still need)> In each case you shall search functions geom_hline or geom_abline > > http://stackoverflow.com/questions/13254441/add-a-horizontal-line-to-plot-and-legend-in-ggplot2So I don't want a straight line> ggplot is rather complicated but very flexibleI don't mind ggplot being complicated, but I find the documentation a little impenetrable.
