similar to: histbackback function

Hi, I am trying to use CART to find an ideal cut-off value for a simple diagnostic test (ie when the test score is above x, diagnose the condition). When I put in the model fit=rpart(outcome ~ predictor1(TB144), method="class", data=data8) sometimes it gives me a tree with multiple nodes for the same predictor (see below for example of tree with 1 or multiple nodes). Is there a way

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),

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 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, 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

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.

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

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]]

Hi there, I am wanting to create 8 side-by-side histograms which have been rotated 90 degrees clockwise from how they usually sit.. all with the same scales. Is someone able to help me out?

Ok, now we have the mapping of color names to color codes (see below) and conversion to rgb (something like Ben Bolker's function), but how to convert rgb to hsv? Thanks to Brian Ripley, Peter Dalgaard and Ben Bolker Details below Regards Jens etc/colors.big maps 455 names to rgb in S syntax etc/rgb.txt maps 657 names to rgb in C syntax, but unlike colors() it has mixed upper and

Hi! If I'm plotting 2 variables with the same units (i.e. wing length of 2 species), how can I force that X and Y axes have the same size for length unit? For example, if X ranges from 0 to 10 and Y ranges from 10 to 30, I want Y axis to be twice as long as X axis. I know I can just put xlim and ylim from 0 to 30, i.e., plot(runif(10,0,10),runif(10,10,30),xlim=c(0,30),ylim=c(0,30)) but this
