Hi, I try to make a histogram from a variable that contains the number of shoots from about 1000 individuals from a specific plant species (the range is 1-110). Those numbers are highly skewed to the right. My question is: how can I make my own classes with the lattice "histogram"? I tried it with "breaks=c(0,5,10,15,20,25,110)" but my "25-110"-class is presented

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

Dear R helpers: Let's say I have some data X, X <- runif(1000, 1, 10000000000) pdf('X.pdf', width=100,height=5) hist(X, breaks=1000) dev.off() I find that, on x-axis the coordinates are 0e+00, 2e+09, 4e+09, 6e+09, 8e+09, 1e+10. Only five numbers, which is too sparse in a 100x5 pdf file. I want the x-axis coordinates to become more dense, e.g.

Hello list! I would like to fit a distribution to each of the peaks in a histogram, such as this: http://photos1.blogger.com/blogger/7029/2724/1600/DU145-Bax3-Bcl-xL.png . The peaks are identified using Petr Pikal peaks function ( http://finzi.psych.upenn.edu/R/Rhelp02a/archive/33097.html), but after that I am quite stuck. Any idea as to how I can: Fit a distribution to each peak Integrate the

In case people on the list don't know it, A Vorbis tester (who's email I've lost! If you're on the list, speak up!) is maintaining a vorbis audio quality test page: http://hem.passagen.se/ingets1/vorbis.htm He's doing us the great service of hunting down samples that break Vorbis (so we don't have to :-) In any case, it turns out that the trumpets in the dr4 sample

I have two .txt files with lists of generated data I want to plot them on the same histogram. I'm aware of the histbackback function, but that is not really what I am looking for, I just want them on the same histogram but so they are still grouped separately (different colours, different norm curves etc). Does anyone know how to do this? Thank you. [[alternative HTML version deleted]]

Hello, This is a problem for which there seem to be several solutions online, but not really. My question was about plotting a curve over the histogram. All the previous posts and messages talk about generating a *density histogram*using (freq=F) and then plotting the density curve. However, I find that that seriously distorts my data and the plot becomes confounding to the viewer. I was

Hi, I'm using the hist function to plot the frequency of 21 variables, but it keeps starting the x-axis from 0 and adding variables 1 and 2 together (all other vairables have the correct frequencies). I suspect it adds 1 and 2 together so that 0 can fit in with demarcations at intervals of 5. Using "xlim=c(1,21)" to specify that i don't want to include 0 and using the

Dear all, I am trying to plot 3 histograms on the same graph using the following command. hist(x,xlim=c(0,100)) hist(y,add=TRUE) hist(z,add=TRUE) The xlim of y is c(20,21) and that of z is c(99,99.5) , whereas the variable x has xlim at c(0.5,2). Apparently, the graph end of displaying a line only, corresponding to each histogram due to the wide range of the xlim and tightness of the

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

TestHistogram_A is a function that plots a histogram, then returns 3. For me it fails to display the plot, at least in the order given below. TestHistogram_B is a function that plots a histogram, then exits. The only difference between the 2 functions is that B does not return 3. It displays the plot. This problem does not occur when histogram is replaced by boxplot Their use

I am trying to do a histogram lattice plot and I would like the histogram to be filled with a different colour in each panel. Note: I want every bar in each histogram to be the same colour, but that there should be different colours *between* histograms. Can't seem to get this to work. I thought that something like the following would be a goer: set.seed(42) X <- rnorm(200) A <-

Dear R users and helpers, I'm trying to find an example of a histogram plot as an inset (upper right or left corner) of another histogram. Anyone has an example of that?

I would like to make a scatterplot, with a histogram of the x and y variables above and to the right . I can use layout to set up the areas, and hist(x,y) works fine for the upper histogram. However, I need a rotated histogram on the right, and I don't know how to do this. I've seen a solution with a bar plot on the right, but I'd like to use a histogram. Do you know how I can do

I would like to add some vertical lines to a lattice plot of histograms. What I am after is a lattice version of abline(v = 1234). The lattice histogram plot is just: histogram( ~ LTSE | approach, data = arrivals) Can anyone point me in the right direction for this?

Hi, I've had some trouble figuring out how to produce a histogram in R directly given a frequency table or relative frequency table. I've looked through the documentation and mailing list, and have only found information on producing histograms given the original data set. Any help would be appreciated! An example of what I'd like to do would be to take the following frequency table:

Hi I would like to superimpose group-specific densityplots on top of an overall histogram using panel.histogram and panel.densityplot. Furthermore, I would like to automatically adjust the range of the y-axis to take into account the ranges of both histogram and densityplot. This last part is where I have a problem. I believe using the prepanel argument of histogram is typically the way to go,

Dear All, I have a massive dataset from which I would like to draw a histogram. Any ideas on how to accomplish this? Thanks in advance, Paul

I want to make a histogram in R of the data in attached excel file called 'cbt'. However, I need the histogram to show a separation for Group 1 and Group 2, as in attached image. How do I do this in R? I know how to make a histogram for a single group, but how can I separate the 2 groups? http://r.789695.n4.nabble.com/file/n4256052/hist.jpg
