similar to: ggplot2 histogramm

Given a data frame with a continuous variable and a factor. I would like to generate a histogram of the continuous variable, where each bar is filled with different colors according to the percentage of factor values falling into this region of the continuous variable. I looked into packages like 'lattice' and 'ggplot2'. Searching R-help revealed that 'histogram' is

Hello My data looks ugly in a normal histogramm. How can I create a histogramm with a Y-axis in log-scale? Thanks for your help! David Graf --

Hi, My question is in the subject. Here, a picture that's illustrating my problem : http://r.789695.n4.nabble.com/file/n3248321/graph.png This figure comes from an article published in Cancer Cell by K.E. Gascoigne and S.S. Taylor in 2008. Thanks you very much and sorry for my English. -- View this message in context:

thank you for your answer i checked my code and it now works One more question... do you know how to have an 3D histogramm from a known matrix of probabilities Cline >From: "David Barron" <mothsailor at googlemail.com> >To: "C?line Henzelin" <celine_appui at hotmail.com>, r-help ><r-help at stat.math.ethz.ch> >Subject: Re: [R] (no subject)

hello, i am using the hist function with classified values. The class breaks are >1, so histogram$density is != 1. How to plot the histogram with freq=FALSE and the real class density values. I used: > h2 = hist(value, breaks = breaks_vector) > h2$density = round(h2$counts/sum(h2$counts), 2) > h2$intensities = h2$density > plot(h2, freq=F) but this isn't the best way, i

Hello there! When I do freq=F on hist, I get on the left a small number, what exactly does that mean? Thanks, Martin

Hi, have anybody a hint how i could avoid the cumbersome way (..especially the value part) change the data representation from n column data.frame to an stacked representation. many thanks Christian #example data dfw <- as.data.frame(matrix(runif(10*10),ncol=10)) dfw$group <- sample(c("X","Z"),nrow(dfw),replace=T,prob=c(0.75,0.25)) # change var <-

I am getting following strange error : library(sn) library(ggplot2) dat1 <- as.matrix(rsn(1000, 0, 1, 0))[,1] ggplot() + geom_histogram(aes(x = dat1, y = ..density.., fill = ..count..)) + xlab("Distribution") + scale_y_continuous("") Error: No data for layer Can anyone please tell me why it is coming? -- View this message in context:

Hi, I just tried to boot my token ring devices with 2.05 - to no avail, it hangs after loading the kernel. I then tried older versions, and found 2.03 booting like a charm, and every 2.04-pre including 2.04 hanging. Here's the config of the devices: - Networkstation 2800 with IBM PCI Token Ring card 2 - IBM Thinkpad T21 with IBM PCI Token Ring card 2 Maybe this has to do with the changes

Hi! Thanks for taking the time to read this. The code below creates a graph that takes 100 samples that are between 5% and 15% of the population (400). What I'd like to do, however, is add two other sections to the graph. It would look something like this: from 1-100 samples take 100 samples that are between 5% and 15% of the population (400). From 101-200 take 100 samples that are between

Hola de nuevo. Resulta que al actualizar a la versión 0.9.2 de ggplot2 , ahora en mi eje continuo y , los valores se etiquetan en formato científico , cuando antes era normal. Es decir, mis valores máximos están sobre 300000, pero en el eje ahora pone 3e+05 y no he encontrado como cambiarlo. He visto que se puede cambiar utilizando el paquete scales y utilizando por ejemplo , siendo p un

Hi, I have a question related to the newest version of ggplot2 (0.9.0). I just updated this morning and from CRAN it looks like the Mac version is the only one at 0.9.0 as of right now. http://cran.r-project.org/web/packages/ggplot2/index.html Anyway, I was in the midst of a project where I was trying to replicate "Back-to-back Bar Charts" in this blog post.

Hello, this following code give a nice png: /library(ggplot2) i <- 1 png(file=paste('test ',i,'.png',sep='')) qplot(carat, data=diamonds, fill=color,geom='histogram')+scale_y_continuous(i) dev.off() / I would like to get more files, but the following code doesn't make any file: /library(ggplot2) for (i in 1:2) { png(file=paste('test

Dear All (probably Hadley), I am now trying to customise some plots using a bar geom. I do not want to use the default binning statistic, but rather calculate the bar heigths separately. I do manage this, but for comparison purposes I would like to have a set of plots all with the same y-axis height. But I do not seem to find out how to fix the scale of the y-axis in this case. Any tips?

Hi , I would like to use ggplot2 to plot a matrix as an image. You can copy paste the following Data<-matrix(data=rnorm(900,80,20),nrow=30,ncol=30) lengthOut<-5 Lengths<- 15 library(reshape2) library(ggplot2) tdm <- melt(Data) ggplot(tdm, aes(x = Var2, y = Var1, fill = factor(value)),levels=seq(0,1,by=0.1)) +                   labs(x = "MHz", y =

Dear All, I am trying to graph a simple scatter plot where the x axis is year and the y axis is a percentage (percentage of infant death). Instead of plotting the raw data, I want to plot summary statistics such as mean and median. Here is the problem: the value range of y is between 0 and 1, but since infant death is a rare event, the mean and median is very low (something like 5%), which shows

Dear UserRs, I am trying to use systematically ggplot2 for most of my plots, but I am fighting some lack of documentation, which I try to overcome. I want to build a scatterplot where the axes cross exactly at (0,0). I tried using scale_y_continuous(limits=c(0,10)), but I always get an extra space at the bottom of the axes. The code I used is below. > plotdata<-data.frame(x=1:10,

Hi, To my knowledge, an excellent of ggplot with a second y-axis is https://rpubs.com/MarkusLoew/226759 In this example, the author uses two colors for the two lines, but the line shapes are the same -- both are solid. Could each line have its own color as well as its own shape? For example, can I make the red line with the linetype "twodash", while the blue line with the

Dear guRus, after solving serveral other probs with boxplots, my ylabs do not appear correct. They area cut off. I guess I have to change the letf and right margins, but I do not know how. Here is an example: http://frosch.homelinux.org/tmp/plot.png Thats the code i tried to use: <R-code> oldpar <- par() # changing the margins par(mar=c(4.1,5.1,4.1,5.1) +0.1) P <- boxplot(bs.s ~
