similar to: What is the equivalent of column.prods() from S in R?

I'm in the process of converting some S3 methods to S4 methods. I have this function : setGeneric("enrichmentCalc", function(rs, organism, seqLen, ...){standardGeneric("enrichmentCalc")}) setMethod("enrichmentCalc", c("GenomeDataList", "BSgenome"), function(rs, organism, seqLen, ...) { ... ... ... })

Hi, Is there any function to replace colProds that finds column-wise products of a matrix? Or is there any other function that would give a better solution this problem ? I have a matrix and an array, example: > a GSM1.CEL GSM2.CEL GSM1.CEL 10000_at 1 3 1 10001_at 3 3 3 > b 10000_at

Hi all, I am trying to multiply each column of a matrix such to have a unique resulting vector with length equal to the number of rows of the original matrix. In short I would like to do what prod(.) function in Matlab does, i.e. A <-matrix(c(1:10),5,2) V = A[,1]*A[,2] Thank you Graziano [[alternative HTML version deleted]]

Hi, You could try: A<- matrix(unlist(read.table(text=" 1 2 3 4 5 6 7 8 9 9 8 7 6 5 4 3 2 1 ",sep="",header=FALSE)),ncol=3,byrow=FALSE,dimnames=NULL) library(matrixStats) ?res1<-t(sapply(split(as.data.frame(A),as.numeric(gl(nrow(A),2,6))),colProds)) ?res1 #? [,1] [,2] [,3] #1??? 4?? 10?? 18 #2?? 63?? 64?? 63 #3?? 18?? 10??? 4

Dear List I just downloaded and installed R 2.12.0 and then installed R Commander . First it got RCmdr and Car, and then suggested for other packages for utilizing the full functionality- I clicked yes! I got 140 packages installed!!! Cran Mirror was UCLA... Here is the list. Is this intentional- I can see some packages like snow and multicore which are desirable but quite optional.(see list

(I think this is being caused by the new methods package in RC.) In the RC (March 24) some of my packages are generating a Note Note: Method with signature "MySQLConnection#integer" chosen for function "coerce", target signature "TSMySQLConnection#integer". "dbObjectId#integer" would also be valid This is coming from a call to dbGetQuery() in package

Since S and R are not completely the same, there are delicate differences between S and R, which an S book may be confusing if I want to learn R. One example is Statistical Models

Dear R-help Listers, The following two student competitions are of interests to the now many student R package developers. I'd appreciate your help in spreading them. #1. John M.

Hi, I found the following on Windows 2000/NT R Version 1.9.1 (2004-06-21) (also Version 1.9.0): The S4 group "Math" doesn't work as documented; i.e., "log", "log10", "gamma" and "lgamma" are included in the documentation but don't work. See example code below. Moreover, what about 'genericForPrimitive' which is used in

I am new to R and am currently gathering reference books. In 'An Introduction to R' I have read the following: "For R, the basic reference is 'The New S Language: A Programming Environment for Data Analysis and Graphics' by Richard A. Becker, John M.

Hi, I want to look for some detailed explanation on the properties of Q-Q plot and how the properties are derived. In R, there is the following reference. Becker, R. A., Chambers, J. M. and Wilks, A.

Just to let everyone know: John Chambers R book is no longer at pre-order status on Amazon which is a good thing. The only problem is that now it is temporarily out of stock. There must have been many pre-orders so now I'm kicking myself for not having done that. Mark

Hi, One way of doing object-oriented programming in R is to use function environment to hold object's data, see for example @Article{Rnews:Chambers+Lang:2001a, author = {John M.

I'm surprised this isn't a FAQ, but I searched all over and could not find a reference to it. Chambers (1998) makes repeated references to "Chapters" in S (e.g., p. 6), but I can find no reference to "Chapters" in R. Since Chapters were not used in earlier versions of S, I'm wondering if R uses them or not. If it does, how does one get them to work? I've

I could not find any reference to this in the list archive. I am setting up SAMBA on an IRIX system. The passwd command does not say "Password changed" or similar at the end, it just ends. However, if the command fails for any reason (unable to get a lock on the passwd file, for example) it does report that. My problem is that I cannot see any way to get the passwd chat string to

Does R, or will R, be integrating the changes to the Chambers/Lucent S language under their version 5.0? If not already, then when?
