Hi, I'd like to request that the 'write.dta' command also save the "var.labels" attributes of the data frame. 'read.dta' can read them, but 'write.dta' doesn't write them back. Thanks....

Hello dear R-helpers, I'm working with R-2.15.2 on Windows 7 OS. I'm stucked with a merge of two data frames by characters. In each data frame I got two different list of names, that is my main-key to be merged. To figure out what I'm saying, I build up a modified "?merge" example, with errors by purpose: # Data for authors: authors <- data.frame( surname =

Dear Specialists in R, May be somebody has experiment in using pakage for the book Quantitative Risk Management by McNeil? This package is writen in R. I have run this package for fitting the data to Nornal Inverse Gaussian distribution and fased with following problem. > Return<-read.csv("data.csv") > Transpose<-t(Return) > fit.NH(Transpose, case="NIG",

Hi, ==================== Reproducible example: ==================== data(Animals, package="MASS") # interesting dataset # Run model lm1 <- lm(log10(body)~log10(brain), data=Animals) # Setup 2x2 graphics device par(mfrow=c(2,2)) # Plot diagnostics, label the two most "extreme" points based on magnitude of residuals plot(lm1, id.n=2) ==============================

Dear R users: I'm wondering if it's possible to get the residual correlation matrix when using factanal. Since factanal assumes that the errors are normally distributed and independent (provided the factor model fits the data) this would be useful. Of course you would need to submit the data to the function to get the residuals (not just their correlation matrix), but it should be possible

Yes and no. Given your response it appears that "Proper Case" is not a term that everyone uses. In Excel there is a function "Proper" which in essence changes "this line into something like this" into "This Line Into Something Like This." My look at casefold seesm to be that is is a wrapper of two functions to change text into either Lower or Upper case.So

Full_Name: Edward McNeil Version: 2.5.0 OS: Windows XP Submission from: (NULL) (203.170.234.5) This is a new bug introduced to R2.5.0. Scenario: If one of the data frames to merge contains two variables that have the same name, then the data in first variable (of the same name) is copied to the second variable in the resulting merged data frame. In R2.4.1, the second variable name is

I'm not sure if this is the right mailing list. My apologies if I'm sending the question to the wrong mailing list. (The r-packages list moderator suggested using the R-help list.) My question is about the "chickwts" data in the datasets package. According to help(chickwts), the source of the data is ?Anonymous (1948) Biometrika, 35, 214. But this reference seems irrelevant.

I am probably just looking in the wrong place. I am sure there are a number of ways to do this. If anyone could point me in the right direction it would be very much appreciated.

Dear List, As someone who is in the process of trying to migrate from Excel, I'd appreciate any help on this question: I have a data set and want to fit, say, three distributions to it. I would like to create a plot that shows my data points against all three fitted curves (estimated d.f.). Basically, I lookint to creat a plot that looks like the one presented in the attached paper (Figure

Dear all I am trying to compare the performances of several methods using the AUC0.1 and not the whole AUC. (meaning I wanted to compare to AUC's whose x axis only goes to 0.1 not 1) I came to know about the Mcneil Hanley test from Bernardo Rangel Tura and I referred to the original paper for the calculation of "r" which is an argument of the function cROC. I can only find the

Hello, I am making some use of ROC curve analysis. I find much help on the mailing list, and I have used the Area Under the Curve (AUC) functions from the ROC function in the bioconductor project... http://www.bioconductor.org/repository/release1.5/package/Source/ ROC_1.0.13.tar.gz However, I read here... http://www.medcalc.be/manual/mpage06-13b.php "The 95% confidence interval for

Thanks Ján! >What were the exact changes you were trying to make? I was following this guide: https://wiki.archlinux.org/index.php/PCI_passthrough_via_OVMF#Passing_keyboard/mouse_via_Evdev Specifically, I was updating the domain tag to include `xmlns:qemu=' http://libvirt.org/schemas/domain/qemu/1.0'` >both call virDomainDefineXMLFlags under the hood. That is good to know,

The following code produces an eps file with the tops of each of the ylabs clipped off. par(mfrow=c(2,2)) plot(runif(10), ylab="Function(Lengthy Expression)",xlab="Prediction") plot(runif(10), ylab=expression(Delta * Beta^2),xlab="Prediction") plot(runif(10), ylab="Function(Lengthy Expression)",xlab="Prediction")

I am trying to create a new variable which uses the suburb names if HR and HRRES are the same but which uses HRRES if they are different. Any assistance would be appreciated as my brain has just packed up. I'm not sure I can teach myself anymore new tricks this afternoon. HR HRRES SUBURB What I am trying to get 954 Wheatbelt

Hi I have two lots of numbers which I would like to histogram using the hist() function. For comparative reasons, I want them to be on the same scale, which I can use the xlim and ylim options to achieve. However, having them on the same scale is meaningless unless they have the same "breaks". Consulting the documentation, there are 4 ways of defining the number of breaks, only one
