Hi, I would like some extra information on the 'cgh' package in R. I noticed that there isn't much activity regarding this package on the R and BioC mailing list (I googled it). I started using this package and I have few questions: 1/ As I have a custom tiling like array @8um features resolution (affy), I have a lot of probes to work with. I'm assuming it is correct to

This is a question and maybe an announcement. We've been discussing in the group that it would be nice to have a mechanism for something like "inline" C/C++ function calls in R. I do not want to reinvent the wheel, therefore, if something like that already exists, please give me a hint -- I could not find anything. If not, here is a working solution, please criticise so I could

Hi I've written the following program: #include <R.h> #include <Rdefines.h> #include "Projector.h" SEXP Projector2(SEXP L, SEXP G, SEXP W, SEXP xymod, SEXP modif){ int nprot=0; PROTECT(L=AS_NUMERIC(L));nprot++; PROTECT(G=AS_NUMERIC(G));nprot++; PROTECT(W=AS_NUMERIC(W));nprot++; PROTECT(xymod=AS_INTEGER(xymod));nprot++; PROTECT(modif=AS_NUMERIC(modif));nprot++;

I have the following contrived code in package format. On Solaris and Mac OS X, code runs just fine. On Windows, it crashes the R environment with the "Send Bug Report" dialog. I tried R 1.8.1 (Win2K) and R 1.9 (WinXP) binaries with the same result. PCs otherwise appear properly configured for creating R packages. Anything blatantly wrong? Suggestions? TIA Relevant files from package

I've been studying some of the code and I'm still a little shakey on the proper method for returning a data.frame from a C function (which is my ultimate goal here). I've started some code that I've "stolen" from the archives and I'm running into crashes, etc. I've been trying to gleen some insight from the src/main/scan.c file and didn't find many comments in

I have the following data: intens<-c(28000,72000,120000,150000,180000,260000,310000) #Td peakcb<-c(1.2,2.5,2.7,3.7,5.6,6.2,6.8) #presses/s peakan<-c(0.5,3.7,5.1,5.8,7.4,NA,8.4) (See why I am using NA? I can work around this problem by using intensityan and intensitycb) Now do a plot of peakan: plot(intensity, peakan, pch=10,type="b") The plot skips the point (260000,NA),

I am using C code to create an S4 object based on Douglas Bates's example in his lecture notes on <http://www.ci.tuwien.ac.at/Conferences/DSC-2003/Tutorials/RExtensions/slide s.pdf> http://www.ci.tuwien.ac.at/Conferences/DSC-2003/Tutorials/RExtensions/slides .pdf e.g. SEXP La_DGE_dc(SEXP A) { SEXP aa = PROTECT(duplicate(A)); SEXP adims, pivot, val; int

Hi, I am the current webmaster at WUML (www.wuml.org) a college radio station. We are looking to purchase a new web cast server which we are planning will run IceCast, but it is a little unclear on the system requirements that IceCast requires. I read somewhere that IceCast can run on as little as a 486 with 32mb of ram but that sounded like those specs were for streaming mp3s saved on that

Hi, Below I have a mickey-mouse example using Oleg Sklyar's wonderful inline package. The question I have is, how do I return multiple values, say in a list? Inside the C code, I've also calculated 'sum'. How do I return this along with 'res'? Ultimately, I want to return multiple matrix results. Thanks in advance for any code snipplets/advice! Regards, Ken #

I'm trying to setup a couple of Cisco 7960's in asterisk. I have asterisk working fine for sip clients, and can call the 7960's just fine, but I can't seem to dial out on them. As soon as I enter the first digit, the phone attempts to dial it without waiting for the rest. I've changed timeout settings, etc but can't seem to get it to work. Any ideas? Asterisk

Hi, all! My project today is to write a speedy colSums(), which is a function available in S-Plus to add the columns of a matrix. Here are 4 ways to do it, with the time it took (elapsed, best of 3 trials) in both R and S-Plus: m <- matrix(1, 400, 40000) x1 <- apply(m, 2, sum) ## R=16.55 S=52.39 x2 <- as.vector(rep(1,nrow(m)) %*% m) ## R= 2.39 S= 8.52 x3 <-

Hello to all, I'm trying to build a PBX using Asterisk. I have a single BRI ISDN line and I need to connect 4 internal normal phones and a couple of softphones on PC. I have bought a single port Billion S0 card and a TDM400 with 4 FXS modules for the intenal phones. ISDN lines here in Greece terminate to an NT1 terminal called NetMod

Dear list! I have a little problem, trying to enable logging of deny rule. I have enabled it via kernel: options IPFIREWALL options IPFIREWALL_VERBOSE options IPFIREWALL_VERBOSE_LIMIT=3 It is ipfw2. After that, my inten- tion was to use syslogd and !ipfw *.* /var/log/ipfw.log and newsyslog with /var/log/ipfw.log 600 3 100 * J In rc.conf I have firewall_enable="YES"

Hello, I am trying to convince our IT Manager that R is as safe as possible from IT security point of view - could you point me to something on the web / some reasons for why this is true? I do not think he has a specific concern but does not know the software and would like to understand the security implications. Thanks in advance Best Regards Martin Hanek Actuarial Analyst Glacier

I am trying to use a meta data set with information about some repetative analysis that I have to do for a variables measured on multiple occasions. I think the best way to explain the problem is by using a simplified example. So here goes: I have a data frame called "meta" say with the following content: Test Min Max Low High APS 0 40 -10 10 TPP 0 120 -8 8 NOS

Dear Martin, Have you try to create a new variable for age squared, say agesq? If you fit the model using this new variable you should get the coefficients. So your new model is something like height~age+agesq I hope this helps, Saghir > -----Original Message----- > From: MARTIN Ludovic [SMTP:martinl@mathinfo.ens.univ-reims.fr] > Sent: Wednesday, 07 May, 2003 2:02 PM > To:

Hi, I have followed the recommended steps for creating a package (rctest). As of now, my goal is simply to understand how various pieces fit together. The package includes: (1) C code with source in sub-directories, compiled to create a static library. (a) There is a single C-struct (dns) a simple 'matrix': {int m; int n; double *d;} (b) C code to create random matrix of a certain size.

Dear all, I am testing a simple C++ function that takes a double matrix as argument and which uses routines provided by the C++ Armadillo package. I am aware of the nice capabilities of Rcpp and RcppArmadillo which helps simplifying a lot and that I have already successfully tested. However, I had a hard time trying to figure out how the coercion from a REALSPX matrix to an arma::mat =
