Hello, To indicate probability densities instead of counts on a histogram, I specify freq = FALSE. However, I expect that summing all top y coordinates over all the intervals of the histogram will provide 1. 1) v <- c(0.2885, 0.2988, 0.3139, 0.2615, 0.3179, 0.3163, 0.2583, 0.3052, 0.2527, 0.3147, 0.3235, 0.2408, 0.2480, 0.3108, 0.3577, 0.2829, 0.2694, 0.3275, 0.3314, 0.2639, 0.3076,

I'm trying to do something very simple... I wan to plot a histogram where the y axis represent the percentage of the total sample that each bin represents. I know how to plot a histogram with the counts and density... but can't find anything that gives me perenct of sample on the y axis. Any help is appriciated Below is the script I'm working with par(mfrow=c(1,2))

Hi, I am searching for a possibility to display a logarithimic y-axis in a histogram. With plot that's easy (e.g. plot(1:10, log="y") but for histograms this does not work the same way: I tried hist(rnorm(1000), freq=FALSE, seq(-4, 4, .5), ylim=c(0.001, 0.5), log="y") Which gives the expected histogram but also warnings for my log="y" command

Dear all, I'm creating a histogram with the function hist(). But right now what I get is column representation (as normal). I'm wondering if I could switch X-axis and Y-axis and get row-representation of frequencies? One more question, can I define the step of each axises for the histogram? Thanks so much! Donghui

I have what is probably a simple problem. I have a data file from an MCMC Bayes estimation problem that is a vector of 500,000 numeric values (just one variable) ranging from 100,000 to 700,000. I need to display the histogram of this data in a high quality graphic for a figure in a journal publication. I want 100 bins so as to display a reasonable complete and smooth histogram, and I need the

All, I have been trying to get calls to hist(...) to be plotted with the y-axis having a log scale. I have tried: par(ylog=TRUE) I have also looked at the histogram package.

Dear useRs, Is there a way one can add x-axis values to a histogram? Example: z = rgamma(n=1000, shape = 8, scale = 1000) hist(z, breaks = 30) Currently I see 4 x-axis values: 5000, 10000, 15000, 20000. Can I add more values or modify the ones currently showing? I tried ?hist, yet couldn't work this out. Thank you very much. ----- ~~~~~~~~~~~~~~~~~~~~~~~~~~ Diego Mazzeo Actuarial Science

Is it possible to change the x-axis values in a histogram to reflect binned values? Here are my data: histexample<-c(6,7,7,8,8,8,9,9,9,9,9,10,10,10,10,10,10,10,11,11,11,11,11,11,12,12,12,12,13,13,13,14,14,14,15,16) hist(histexample) Now, I'll bin pairs of adjacent values together (e.g., 5-6, 7-8, 9-10, 11-12, 13-14, 15-16) using the following bins<-c(4.5,6.5,8.5,10.5,12.5,14.5,16.5)

Hi, I'm trying to create a histogram with R. The problem is that the frequency is high for a couple of x-axis categories (e.g. 1500) and low for most of the x-axis categories (e.g. 50) http://r.789695.n4.nabble.com/file/n2237476/LK3_hist.jpg . When I create the histogram, it is not very informative, because only the high frequencies can be seen clearly. Is there any way I could cut the

Dear all Problem: hist()-function, scale = ?percent? I want to generate histograms for changing underlying data. In order to make them comparable, I want to fix the y-axis (vertical-axis) to, e.g., 0%, 10%, 20%, 30% as well as to fix the spaces, too. So the y-axis in each histogram should be identical. Currently, I have 100 histograms and the y-axis scales changes in each. Here is my code:

Hi: The y axis on the hist function seems to set its limits oddly. sometimes, it covers the full range of the data and sometimes it stops one major tick short. I have had this behavior with a variety of data sets, and it can easily be reproduced by just running the following several times: hist(rnorm(100000)) I have tried explicitly setting ylim to the range of values produced by rnorm

Dear R- list, I have some data to present with histograms. Therefore I used hist(...). I have few values with almost 80% of the frequencies (totaly 800) and some other values with low frequencies ( totaly 5 -10 ) that I want to emphasize. Therefore I want to "cut" the y-axis on 100, but I don't know how to deal with this. Thanks in advance, Michael Graber

Hi, I have a query regarding usage of hist (histogram) function in R. I have a data where the range of the x -axis is from 0.0-1.0. When I use hist the ticks on the x-axis it gives me by default is at 0.0,0.2,0.4,0.6,0.8 and 1.0. If I want more ticks such that the x-axis has 0.0,0.1,0.2,0.3...till 1.0 what parameter should I use in the hist function? Thanks manisha

I have the following data which I tried to draw the probability density plot. Here is the code I have: x <- read.table("mydat.txt"); d <- rep(x$V2,times=x$V3); hist(d,probability=T, xlab="FlowSignal"); But why the y-axis range from 0 to 6, instead of 0 to 1? What's the correct way to plot it? #id flowsignal frequency 1 0.67 1 1 0.70 1 1

Hi, I'm plotting a multiple histogram using the function multhist {package plotrix}, something like: library(plotrix) mh <- list(rnorm(200, mean=200, sd=50), rnorm(200, mean=250, sd=50)) multhist(mh) In this graph y-axis represents the frequency of observations.... but I would like it to be scaled into relative frequencies, does anybody know how to do this with multhist or similar

I am currently trying to create 3 histograms from 3 sets of data and in order to compare them I need them all to have a common scale, the Y axis is the only place its a problem, as one histogram only goes up to 4, another 5, and another 7 on the Y axis and obviously they all need to be in the same scale to allow comparisons. Can anyone help? Thanks, Feargal -- View this message in context:

Dear All I am using the histogram() function to plot two subsets from my data on the same output display, i.e. there are two histogram plots My code is: histogram( ~ Age | Date, layout = c(1, 2), xlab = "Age (years)", strip = FALSE, strip.left = TRUE, col = "black", border = "white", cex.axis = 1.1, family = "serif", cex.lab =

Earlier, I posted the following question: I want to superimpose histograms from three populations onto the same graph, changing the shading of the bars for each population. After consulting the help files and the archives I cannot find out how to do this (seemly) simple graph. To be clear, I want - a single x axis (from -3 to 18) - three groups of bars forming the histograms of each population

Dear all, I have done further modifications on the histogram functions that I reported earlier this year, and I hope this can be of use and perhaps included in the distribution. I have been using this stuff a couple of months myself, and while it is nothing sophisticated, it has it's applications. :-) I did a few small modifications today to make it a bit more compact. I have modified the

Hello! Up to now I have been using hist() to display the distributions. Howevere, I noteiced strange numbers on y (vertical) axis, if I used probability = T or freq = F option. I thought it is a bug and launched the R-bug system and found some posts on that matter. Brian Ripley responded to one, that one should look at truehist() for that. Ok I can use truehist() if I want to see the ratios
