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

R never gave me any serious problems until I tried to use it on Windows XP. I had 1.8.1 installed and working successfully for a few weeks. This morning when I launched it, I received this error message: "R for Windows GUI front-end has encountered a problem and needs to close. We are sorry for the inconvenience." I downloaded 1.9.0 and installed it, but when I launch it, I get this

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

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

Hi! I am looking for a R library by which i can load images (i found pixmap that allows it to do). But in addition i need methods to access the data, get them for example as an array or matrix to do with this data some processing. 1. Is there a method in the pixmap library to access the matrix in which the image data is stored. 2. Is there an alternative library running under MS Windows?

hello I am returning to some libraries that I had previously customised by amongst other things adding additional functions. I had simply typed these new functions into the file in library/R/thelibrary. These however do not seem to be loaded now as they previously were under older versions of R. What's changed and what do i need to do? Thanks Stephen

Hi The cor function in the stats package calculates the correlation between columns of data, does anyone know if it is at all possible to calculate the correlation between rows instead ? Or is there an appropriate package or function that is more appropriate I'd like to calculate spearman & pearson correlations between rows. Many thanks Jason -- --------------------------------

Hi, I've read a few manuals, and it got me confused on what's the correct way to mimic NT PDC, and I hope someone can help me. According to IDEALX Samba PDC Guide 1) Samba 2.2 deal with only 2 groups, Domain Admins and Domain Users. Are these hardcoded or do I add to the domain admin group? Do I add it such as domain admin group = "Domain Admins"? 2) Seems that from the

Hi!! I am a new user of R (just trying to analysis microarrays with some packages from the bioconductor project). I would like to import a text-delimeted file containing 20 columns and 22200 rows. I have tried read.table; scan(file="") <matrix(scan("file", n=20*200,20,200, byrow=TRUE)); Doesn't matter what I try I got the next message: error in file (file

This seems like a bug to me. Can someone verify this? First we define a function f that returns its second argument and lapply it to 1:2 using 9 as the second argument and all seems well. Note that "{" as a function does the same thing as f, as illustrated with f(1,9) and "{"(1,9); however, when we attempt to use "{" in the very same way we used f in lapply,

Hi! I encountered some things trying to build own packages under Windows 2000 for which i found no answer in the documentation. First. 1. I do not found the rcmd.exe in the bin directory of R_HOME. I installed R using the setup.exe 2. I updated the R intatllation with one of the zip files. (rw1041sp.zip) now i had the rcmd.exe in the bin. 3. I do not found any hint in the docu that perl is

Hi! I guess that it cant work. but maybee I am wrong. I would like to define a function rbind. > rbind function (..., deparse.level = 1) { which works only for objects of class Myclass Is it possible to use something like setMethod("rbind",signature(...="Myclass",deparse.level="numeric") This gives an error. Or should I use rbind.Myclass Eryk. Dipl. bio-chem.

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

Hi! I would like to give my objects functions like "subset", "union", et cetera and name it also in this way. But this functions names are already used in the base package and they are not generic. I am right in that if they would be generic then i still can use the neat names with my objects? I have the impression that there are more and more packages are going to be

Hello All: This function obviously fails x <- function(z) paste("go", z, sep = ".") <- 10 x("now") But is there a way to define the name of a variable through passing a parameter in a function call? Thanks, ANDREW
