Another newbie question. I've written a function and saved the file as Xtabs.R, in a central place on a network so others will be able ot use the function, My question is how do i call this function? I've tried to chance the working directory, and tried to load it via; > library(Xtabs, lib.loc="//filer/common/technical/surveys/R_test") but neither seem to work? the function

I have an R file R_test.R saved in C:\R_test folder. The R_test.R looks like this: setwd("C:/R_test") rnorm(100) write(rnorm(100),"data.txt") q(save="no", runLast = F) Next I would like use an Excel VBA/macro Shell() function to call R and execute R_test.R file. The syntax is *Shell(pathname*[*,windowstyle*]*)* I wrote an Excel macro RunRcode like this: Sub

Hi, Sorry to bother, but I checked around and did not succed creating a bundle from six existing packages (which are checkable, installable, etc. individually). I carefully followed the procedure given in ch. 1.1.5 Package bundles. However, I am getting hoffmann at fluke:~/R/Sources >R CMD check cwhmisc * checking for working latex ...

Hi, After some reading and experimentation I found that I cannot solve this problem: 1.

Hi list, I have not been successful in finding out from the available documentation how under Unix/Solaris to update a packages which I downloaded from the net as the original *.tar.gz and stored in a local file, say (1) home/woodstock/hoffmacw/R/Sources/pack.tar.gz A lot of installed libraries are residing in (2) home/woodstock/hoffmacw/R/library/ but it is unclear to me, how to proceed,

Hi, I'm running Samba as a PDC on a Debian Etch machine (3.0.24-6etch9). It's been some time (months, maybe 1 year) since I last added a new machine to the domain, but I'd need to do it today and I'm getting an error: #>pdbedit -a -m Woodstock-VMXP tdb_update_sam: struct samu (woodstock-vmxp$) with no RID!

PTAk_1.1-1 ( Principal Tensor Analysis on k modes) has been released on CRAN A multiway method to decompose a tensor (array) of any order, as a generalisation of SVD also supporting non-identity metrics and penalisations. 2-way SVD with these extensions is also available. The package includes also some other multiway methods: PCAn (Tucker-n) and

I've got a WD My Passport Ultra 1TB (USB) plugged into my router and I have 4 Windows machines, all running Windows 7, and all 4 machines can see the device as drive 'Y'.

Dear R helpers, I wish to use the "sum" operator for each row of a data frame. However, it appears that the operator acts on the entire data frame, over all columns. What is the best way to obtain row- wise operation? The following code shows my attempts so far, and their problems:- test1=array(rbinom(120,1,0.5),c(20,3)) test1[,3]=NA sum(test1[,1:2]) test1[,3][sum(test1[,1:2])>=2]=1

Hi Helpers, Does anyone know how to read jpeg, bmp or png files into R? I have some photos of brain scans and I want to quantify some aspects of their size. I might be able to do this with the 'locator' function, if I could figure out how to read the files in and make them into an image that I can display on the R Windows device. I have experimented with readBin, using a simple

Jonathan, Try making a list instead of an array. See ?list. Also, did you look into random forests? I'm not sure what you want to do, but there might be methods there to do some of the work for you.

I'm trying to do a little system hacking on CMU Lisp. Currently CMU Lisp has a minimum of two files needed to execute. One is a program usually called "lisp" that the OS runs, which basically a loader for the other file, a lisp.core file that contains the actual lisp system. People have been asking for a way to make a "lisp executable" meaning putting everything into a
