similar to: Installation on Windows XP

I've had a interesting day with R; can anyone offer any advice? First with R 1.8.1. on XP Pro: "R for Windows GUI front-end has encountered a problem and needs to close. We are sorry for the inconvenience." I then tried installing 1.9.0. and got the "information" dialogue: "Fatal error: INVALID HOMEDRIVE" instead of a functioning R! I attempted to set

I installed R project 1.9.0 on Windows XP. The installation went well. Then, I rebooted. Next, I clicked the icon under Programs in the Start menu and received this error, "Fatal Error: Invalid HOMEDRIVE". I clicked OK to the error message. The program does not start. I went to a DOS prompt and did "echo %HOMEDRIVE%" and it returned "C:". This letter is a valid

All, I've encountered the same problem as others who have posted under the same subject. I've had R-1.8.1 installed and running since it was released. Yesterday morning when I tried to start Rgui.exe I got the subject error message. Since I live at the whim of the network administrators I can only assume it was a recent MS critical update. I tried installing R-1.9.0 but no joy. I

Is there a function that provides the Fisher information matrix for a generalized linear model? I do not see how to access the off-diagonal matrix elements of the value returned by glm. (I'm particularly interested in logistic regression.) If not, what is a good way to use R to compute Hessians or other partial derivatives of log likelihoods? I would appreciate any guidance. David

Does anyone know how to use the equivalent of debug() on an S4 method? I would like R to enter the browser not for the generic function, but for the method of the class that I specify.

Given a numeric vector of observations, does R have any generic way to estimate the parameters of commonly used distributions (exponential, gamma, etc.) without numerically optimizing the likelihood function?

Hi, Main objective: Let Rgui find my ~/.Rprofile and ~/.Renviron files, where ~ is equal to getwd("~"). I have few comments/questions: (A) On my WinXP Pro installation, the system environment variable 'HOME' is not availble to R, e.g. Sys.getenv("HOME") is empty. I believe this is default case (correct me if I'm wrong). However, if I set the "Start

Is there a way I can get R to automatically enter the browser inside a user-defined function on the generation of an error? Specifically, I'm trying to debug this: Error in as.double.default(sapply(lis, FUN)) : (list) object cannot be coerced to double In addition: There were 38 warnings (use warnings() to see them) > traceback() 8: as.double.default(sapply(lis, FUN)) 7:

Is there any R function that computes the convolution of the double exponential distribution? If not, is there a good way to integrate ((q+x)^n)*exp(-2x) over x from 0 to Inf for any value of q and for any positive integer n? I need to perform the integration within a function with q and n as arguments. The function integrate() is giving me this message: "evaluation of function gave a

Dear friends - windows R 3.3.3 - sorry to ask a simple question - but I cannot make setwd work properly in scripts In the example below I have made a directory in C (firstdir) and a directory in that (secdir) and the intention is to change directory to the second from the first - it works when I put the entire path but not the tilde - what am I missing? I was around rwf 2.14 as per the help

Hi all- Some recent change...perhaps a windows update, or perhaps a change in the network on which I use my computer....has made it impossible for me to start R. When I try to start the program, I get a message that says "Fatal error: invalid HOMEDRIVE". Any ideas on how to fix this? Thanks much Chris ******* Chris Solomon Center for Limnology Univ. of Wisconsin (715) 356-9494

Dear colleagues, I am a beginner of using R. I am involved in some microarray data analyses and found that R is the most common software in this area. I tried to install the free software today. It seemed to be successful in installing, but when I trigger the short-cut, I got a error massage saying 'Fetal error: invalid HOMEDRIVE'. I have no idea where the homedrive was defined (or

What are some effective ways to leverage the strengths of R and Mathematica for the analysis of a single data set? More specifically, are there any functions that can assist with any of the following? 1. Calling an R function from Mathematica. 2. Calling a Mathematica function from R. 3. Using XML or another reliable data format to pass vectors, matrices, and/or lists from one environment to

After reading the help page on set.seed, I am unsure about how to solve the following problem. I need to call function f a thousand times. The list of values returned by f, should be as random as possible. f calls g twice: f <- function(){g1 <- g(1); g2 <- g(2); c(g1; g2)} The function g in turn calls sample and returns a number, but also depends on its argument, so, starting from the

[RFC = Request for Comments] { Yes, the documentation for .Renviron is really not there (but the FAQ...); the rest is in ?Startup } In R's Startup (on Unix only??) {unless --no-environ is specified} ~/.Renviron (if there) is read as an 'sh' script before R is called, then R looks ((for the site-wide Rprofile and then)) for .Rprofile in the current directory and then for

Is there a way to call an R function to work in the background within the same R session? What I have in mind is the equivalent of adding '&' at the end of a UNIX command, so that R can process an intensive command while I execute other R commands. I want to do this in the same R session, rather than with multiple calls to R, so that all my modified objects will stay in the same

Is there any R function that can display a Postscript file that is already in the working directory? For example, if 'graph.ps' is such a file, I'd like to type something like this: > plot.postscript.file(file = 'graph.ps') If no such function exists, I'd be interested in a way to use existing R functions to do this under UNIX or Windows, preferably without a system

Are there any R functions or packages that can compute distributions, expectations, or quantiles of order statistics (or sample quantiles or extreme values) for a given distribution such as a normal distribution? Both exact and asymptotic calculations are of interest. I am already aware of the 'quantile' function of 'stats'. David _______________________________________ David R.

Dear All, I have Windows Vista and I want to install R. However, when I tried to start it after the installation, I received the following message: 'Fatal error. I cannot retrieve the saved data from .RData'. So, in the moment R does not work. Do you have any idea how to cope with this problem? Thanks in advance -- View this message in context:
