Hello, I like to use the package "kinship" (R version 2.2.0). After loading this package the operator %*% doesn't work. Example: R> library(kinship) R> a <- cbind(1:2,rnorm(2)) R> a%*%a Error message: Fehler in a %*% a : keine anwendbare Methode f侟r "%*%" The Message in English: Error in a %*% a: no applicable message for "%*%". What can I do?

Say I have a FOR-loop for computing powers (just a trivial example) for(i in 1:5) { x<-i^2 y<-i^3 } How can I create a data.frame and a 3D plot of (i,x(i),y(i)), i.e. for each iteration Thanks, Serguei Kaniovski -- ___________________________________________________________________ ??sterreichisches Institut f??r Wirtschaftsforschung (WIFO) Name: Serguei Kaniovski

Dear all, I like to extract row names & column names from the named matrix...... like...... a<-matrix(1:6,2) ro<-c("aa","bb") co<-c("dd","ee","ff") dimnames(a)<-list(ro,co) a > dd ee ff aa 1 3 5 bb 2 4 6 from the above matrix "a" I like to extract rownames separately like

Hello R-users! My (simple?) doubt: How to reverse the sequence of axis Y ?? the diagram below illustrate my idea... (default) | | . | . | . | 3 | 2 | 1 | 0 +---------------------------- 0 1 2 3 ... like I want... 0 | 1 | 2 | 3 | . | . | . | | +---------------------------- 0 1 2 3 ... thanks in advance klebyn

Dear, I am looking for the simplification of a formula to improve the calculation speed of my program. Therefore I want to simplify the following formula: H = sum{i=0..n-1 , [ sum {j=0..m-1 , sqrt ( (Ai - Bj)^2 + (Ci - Dj)^2) } ] } where: A, C = two vectors (with numerical data) of length n B, D = two vectors (with numerical data) of length m sqrt = square root Ai = element of A with index

Hello, I'm a new user... I have a function : calculate <- function(x,y) { z <- x + y } I would like to use the result (z) with another function : recalculate <- function(...) { a <- z^2 } But R says that z does not exist... How can I use z in an another function ? Thank you for your answer... -- David [[alternative HTML version deleted]]

Hello R - users, This may sound simple to may people: I have a list of data as follows type value y 7 y 7 y 8 y 8 y 8 y 9 y 9 y 9 y 9 y 10 y 10 y 10 y 10 y 11 y 11 y 12 y 12 y 14 y 14 y 14 y 15 y 17 y 20 y 20 y 20 y 20 y 25

Hi All, This may be trivial in R but I have been trying with out any success. I have a list of 100 elements each having a sub list of different length. I would like to write the list to a ASCII file. I tried with write.table(), after converting my list to a matrix. Now it looks like Robert c("90", "50", "30") John c("91", "20",

Hello there, I would like to simulate X --Normal (20, 5) Y-- Normal (40, 10) and the correlation between X and Y is 0.6. How do I do it in R? Thank you very much Lisa Wang Msc. Princess Margaret Hospital Toronto, Ca

Hello, my problem is that I don't know how long must be an array of double while calling C from R. R-Code: > array <- c(1,1,1) > save <- .C ( "Ctest" , a = array ) C-Code: void Ctest ( double *array ) { ... array = (double*) realloc ( array , new_number * sizeof(double) ) ; ... } The length of "array" will be compute in C. At the end save$a has a length

Dear R-helpers, I apologize for this certainly simple question. I have the following R lines : > m = matrix(1:12 , 3 , 4); > m [,1] [,2] [,3] [,4] [1,] 1 4 7 10 [2,] 2 5 8 11 [3,] 3 6 9 12 > m1 = subset(m , m[,2]>=5); > m1 [1] 2 3 5 6 8 9 11 12 but in fact I would appreciate m1 to be also a matrix, and thus would like to get :

Hello, I would like to compare two different models in the framework of Cox proportional hazards regression models. On Rsitesearch and google I don't find a clear answer to my question. My R-Code (R version 2.9.0) coxph.fit0 <- coxph(y ~ z2_ + cluster(as.factor(keys))+ strata(stratvar_), method="breslow" ,robust=T ) coxph.fit1 <- coxph(y ~ z_ +

Dear R users: I have two set of data, as follow: x<-c(0,0,0.28,0.55,1.2,2,1.95,1.85, 1.6,0.86,0.78,0.6,0.21,0.18) y<-c(0,0,0,0.53,1.34,1.79,2.07,1.88, 1.52,0.92,0.71,0.55,0.32,0.19) i<-1:length(x) I want to sum each (x[i]-y[i])^2/x[i] together, like: >Sum <-sum((x[i]-y[i])^2/x[i]) >Sum [1] NaN Because the denominator shoud not be zero. So I want to overlook those

Dear R users: I have a problem about catch the value from function. I have following two functions (part): fbolus1 <- function() {......... par<-data.frame(Parameter=c("kel","Vd"),Initial=c(0)) check(par) .....} check<-function(par) { if (par[ ,2] <= 0){ cat("\nEnter again (y/n) ?\n\n") ans<-readline() if (ans == "n" ){

Good evening,I am Marta Colombo, student of "Politecnico di Milano". I'm studying Local Regression Techniques such as loess, smoothing splines and kernel smoothers. Choosing "symmetric" for the argument "family" in loess function it is possible to produce a robust estimate , in function smooth.spline and ksmooth I didn't find this possibility. Well, is there a

Hello everyone, I have a problem when loading the library: IlluminaHumanMethylation27k.db I installed the package from zip (from the Bioconductor website), and also installed all the packages it asked for. It went all succesfull: "package 'IlluminaHumanMethylation27k.db' successfully unpacked and MD5 sums checked" But when I am trying to load this library I get an error:

d911d9874801 ("kernfs: make kernfs_notify() trigger inotify events too") added fsnotify triggering to kernfs_notify() which requires a sleepable context. There are already existing users of kernfs_notify() which invoke it from an atomic context and in general it's silly to require a sleepable context for triggering a notification. The following is an invalid context bug triggerd by
