similar to: Two datasets on one histogram

Hi! (a complete newby, but will not give up easily!) I was wondering if there is any way to decouple the axis and tick mark widths? As I understand they are both controlled by the lwd setting, and cannot be controlled independently? For example I might want to create major and minor ticks, which I now know how to do by superimposing two axes with different at settings, but what if I also wanted

Hi, I'm trying to recreate a sensitivity-specificity graph using the histbackback function. The only problem is that these graphs are typically drawn with vertical rather than horizontal bar plots (and the histbackback function only seems to work with horiz=TRUE argument, using "horiz=FALSE" doesn't work). Does anyone know if: 1) there's a different graphing function that

Hi all, Is there an equivalent to predict(...,type="linear") of a Proportional hazard model for a Cox model instead? For example, the Figure 13.12 in MASS (p384) is produced by: (aids.ps <- survreg(Surv(survtime + 0.9, status) ~ state + T.categ + pspline(age, df=6), data = Aidsp)) zz <- predict(aids.ps, data.frame(state = factor(rep("NSW", 83), levels =

I am making frequency histograms using the histbackback function on my 2 datasets. However when I try to use the brks function: foo<-histbackback(log(fie11), log(fie86),ylim=c(0,9),probability=FALSE,axes=TRUE,ylab=("log10 Parcel Size"),brks=16) The graphic results in a 'NA' label for the y axis (no intervals are returned) Also when I use 'summary(foo)' the

How do you label Xtick and Ytick marks with Currency symbols: $2000 instead of 2000? I would like to add dollar symbols to tickmarks on boxplots, histograms and back-to-back histograms. My Examples (requiring the lattice and Hmisc packages): data(case0102, package="Sleuth2") str(case0102) boxplot(Salary~Sex, case0102) histogram(~ Salary | Sex, data=case0102) require(Hmisc) #

I would want to know if it's possible to plot two histograms on the same graphic in order to compare the bins one to one, like a Excel graphic. If it is possible can you help me to do it, because I don't know the exact R-commands.

Hi, I use a vector of data to draw the histogram, but it is different from the graph by SAS. Can you check it for me please? b is a column vector of 4332 hist(b,probability=T,breaks=30,col='lightblue',ylim=c(0,1)) rug(b) When I used rug, I find the records are smaller than 4332. I don't know where I did wrong. Thanks. -- Yi Du [[alternative HTML version deleted]]

Hello, recently I read about the SweaveListingUtils package and now I want to try it out. However, I can not make it work... Below a minimal example. The problem seems to be the following line (generated by SweaveListingPreparations()?): \ifthenelse{\boolean{Sweave@gin}}{\setkeys{Gin}{width=0.6\textwidth}}{}% If I comment out this line, it works. What can I do about this? I am using the

Dear members, I would like to pass the histogram settings to each subset of the dataframe, and generate a multiple figures graph. First, can anyone tell me how to generate a multiple figures environment? I am trying mfrow=c(2,4) and nothing appears. Secondly, I want to pass the following function in tapply() hist(x, freq=FALSE) lines(density(x), col="red") rug(x) how can I manage

Dear Author and Maintainer of Hmisc contributed package, Dear R developers, i noticed a problem with histbackback routine when i installed the last version of R (2.4.1) (With my previous version, 2.3.1, there was no such a problem) If, e.g., you simply edit the command > histbackback(rnorm(20), rnorm(30)) a warning message is printed on the console. Warning messages: 1: argument

I am trying to plot two histograms using histbackback and then adding color to each of the samples. The code I have seen on the R graph gallery suggests the following method of using histbackback require(Hmisc) age <- rnorm(1000,50,10) sex <- sample(c('female','male'),1000,TRUE) out <- histbackback(split(age, sex), probability=TRUE, xlim=c(-.06,.06),

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

Hi all, I want to make a histogram like the one show http://nar.oxfordjournals.org/content/39/suppl_1/D1011/F1.expansion.html here , but I did not figure out how to add the red marks at the bottom of the bars.

I woud like to plot cumulative histograms. Specifically, I have data like Sex M M F M F F M F Height 6 6.3 6.1 5.5 7.2 6.2 5.9 6.0 .... and I want to plot a histogram of the distribution of all heights, colouring the histogram bars according to sex, for example | o | oo o | o oo ** o o = observations of women | o o*o***o * = observations of

Hi I could only find some discussion on this wrt lattice graphics (which I'm not using). Apologies if I'm missing something obvious. I'd like to produce 3 rug plots under a kernel density plot for a population. The population is subdivided into 3 subpopulations, which I'd like the rug plots to highlight. Naturally, when I do 3 rug plots, they all plot over each other.

Dear R list members, I'd like to produce rug plots at the bottom of panels in a trellis display (using the lattice package), but par("usr") doesn't return user coordinates for panels, and consequently rug fails, as the following example (suggested to me by Georges Monette) illustrates: > x <- rnorm(50) > y <- rnorm(50) > f <-

Hi All, I'm trying to add a 'rug' representation of my data to a plot created with densityplot(). While I can do this in the simple case, I can't do it properly when I include the "groups" argument. I have an example below. I am running a reasonably new version of R. print(sessionInfo()) R version 2.12.0 Patched (2010-11-07 r53537) Platform: i686-pc-linux-gnu

Dear Contributors: I have two vectors x and z, and I want to display the histograms of both vectors in the same graph, x in red bars, z in blue bars. If you have any clue on how to do that, I will be very glad to hear it!!!!!! Thanks in advance again, Juan Pablo Fededa [[alternative HTML version deleted]]

Hello, I have a simple question on rug(). Currently there is only one color possible for the rug. Is it possible to plot a the rug with different colors, for each rug item ? Thx. Bjoern
