Dear all, I do not fully understand how ggplot2 handles NAs. See the following example: library(ggplot2) x <- rnorm(150) g <- as.factor(c(rep(c(0,1,NA),50))) mydf <- data.frame(x,g) m <- ggplot(aes(x = x, group = g, color = g), data = mydf) m + geom_density() How do I get rid of the NAs (i.e. the blue colored curve)? I thought ## m <- ggplot(aes(x = x, group = g, color = g,

I am learning ggplot2 commands and I have figured out how to create histograms and density curves but I am not sure how to add a density curve on top of a histogram. Here are the two graphs that I created. ## Histogram t<-rnorm(500) w<-qplot(t, main="Normal Random Sample", fill=I("blue"), colour=I("black"), geom="histogram") w ##Density Curve

Hi all, I am trying to do a barplot in ggplot2 and want to make sure that the legend order is consistent with the bar order, that is the legend order is orig and match; and the bars are ordered in the same way. It seems to me that I can only control one of them. Any idea? library(ggplot2) df <- data.frame(value = rnorm(20), name = factor(rep(letters[1:10], 2), levels =

Hi R help list I'm simulating logistic regression data with a specified odds ratio (beta) and have a problem/unexpected behaviour that occurs. The datasets includes a lognormal exposure and diseased and healthy subjects. Here is my loop: ors <- vector() for(i in 1:200){ # First, I create a vector with a lognormally distributed exposure: n <- 10000 # number of study subjects

I'm still looking for any volunteers in the Boston or New England areas that would be willing to help out at LinuxWorld in February. It goes Feb 14th - 17th, but the expo part is only 15th - 17th. If you can't come all three days, that's fine, but I would appreciate if there were a couple people that could come at least a day or two. Also, If you help out you get a 3 day pass to the

Hello, The call for papers for SCALE 4x, the 2006 Southern California Linux Expo, is now open. This event will be our fourth annual show. It will be held on Feb 11-12, 2006 at the Los Angeles Airport Westin. We are expecting 1,300+ in attendance this year. We are non-profit, community run Linux, open-source and free software conference. If you are working on something you believe the

Hi all, I was trying to draw a stacked density plot like that : library(ggplot2); library(plyr) dat <- cbind(rnorm(300), rep(c(1,2), each=150)) ggplot() + geom_density(aes(x=dat[,1], fill=factor(dat[,2]), position="stack")) + xlab("") + ylab("") + scale_colour_manual(name = "Pallet", labels = c("X", "Y")) Here

Does anyone (Hadley??) know if there's a straightforward way in ggplot2 to get data divided by a single factor to plot as a rectangular grid of subplots? So far I've only been able to get such data plotted as a single row or single column of skinny subplots. The code below gives an example implemented with lattice, and my best attempt in ggplot2 cheers Ben Bolker ------------ g=

Hi R-help I'm trying to create a grid plot in which each plot in the grid contains two density plots (colored by factor) and two vertical lines at the respective medians (also colored by the factor). Using the diamonds dataset as an example, the following commands give me price density plots by factor cut in a single, ungridded plot. p <- ggplot(data=diamonds, aes(x=price)) +

I have a pigeon sive running which directs some of my received mail to the Junk folder. That works just fine. However, a couple minutes later, it is moved to Deleted mailbox and deleted from Junk. At first I thought my client was doing that so I shut down the client and it still happens. Here are the log entries: Jul 2 00:36:31 mail dovecot: imap(doug): copy from INBOX: box=Junk, uid=10842,

hey guys, CentOS has a stand at the LinuxWorld Expo, London on the 25th and 26th of Oct 2006. And we need some help! We need a few people to come down and help at the stand, talk to visitors and generally spread the good word on CentOS! If you are interested and are able to come help, please get in touch with Lance ( lance at centos.org ) or me ( kbsingh at centos.org ) as soon as possible.

Hello, I am having trouble using "optim". I want to maximalise a function to its parameters [kind of like: univariate maximum likelihood estimation, but i wrote the likelihood function myself because of data issues ] When I try to optimize a function for only one parameter there is no problem: llik.expo<-function(x,lam){(length(x)*log(lam))-(length(x)*log(1-exp(-1*lam*

Hi Petr and thanks for your reply, That's the problem I don't want to modify the labels of my legends but the title of the legend in itself inserting my custom text :) Take for example the 1st graph in this tutorial http://www.sthda.com/english/wiki/ggpubr-r-package-ggplot2-based-publication-ready-plots I want to change the "sex" in "sex subscript 2" or "

Hi There are plenty of examples https://stackoverflow.com/questions/6202667/how-to-use-subscripts-in-ggplot2-legends-r https://stackoverflow.com/questions/19507742/using-expressionpaste-to-insert-math-notation-into-a-ggplot-legend which you can modify. If you say "but it wont' seem to work" how can we know what does it mean? Plotmath expressions are rather tricky, especially if

Hi Your approach seems to me rather complicated. I would reshape data before plotting and maybe also change order of levels in resulting variable factor library(reshape2) dfm<-melt(df) dfm$variable<-factor(dfm$variable, levels=levels(dfm$variable)[c(2,1,3,4)]) p2<-ggplot(dfm, aes(x=rep(1:2,4), y=value)) p2+geom_line(aes(linetype=variable))+

I have just published a article (http://masnetworks.biz/node/20) about exhibiting at LinuxWorld Expo and the lessons learned. I heard some talk about some interest in doing the San Fran show.

Hi, I ran your code, but the results were not as expected. After I ran the code by "source", it return No id variables; using all as measure variables > p2 and no line or legend is on the graph (as attached) Am I doing anything wrong? John library(ggplot2) library(reshape2) dfm<-melt(df) dfm$variable<-factor(dfm$variable, levels=levels(dfm$variable)[c(2,1,3,4)])

Listmates, I installed 8.2 on opensuse 10.3 from the opensuse XGL repository to replace 7.6. Compiz works with the nvidia 8600 GT card (512M of GDDR3) on the box, but the ctrl+alt <- -> switching behavior is really bad. In 7.6, the ctrl+alt <- -> desktop switching changed desktops crisply with just the slightest hint of the cube detected during the very short and nice switch.
