Hi, It turns out that two packages (1 Bioconductor, 1 CRAN) define an S4 class called "Annotated": library(S4Vectors) # see (*) at bottom for how to install library(RNeXML) 1st issue --------- getClass() issues the same warning twice: tmp <- getClass("Annotated") Found more than one class "Annotated" in cache; using the first, from namespace 'S4Vectors' Found more t...

FWIW the code in S4Vectors that does what your subset_ROW() does is: https://github.com/Bioconductor/S4Vectors/blob/04cc9516af986b30445e99fd1337f13321b7b4f6/R/subsetting-utils.R#L466-L476 (This is the default "extractROWS" method.)

Hi R-devel, If you did read my survey on Rhelp about reporting, you may have seen that I am implementing a way to handle outputs for R (mainly target output destinations: xHTML and TeX). In fact: I does have something that works for basic objects, entirely done with S4 classes, with the results visible at: http://www.stat.ucl.ac.be/ROMA/sample.htm http://www.stat.ucl.ac.be/ROMA/sample.pdf To

...splaying an object in a cell would be a reasonable solution for this particular problem. However, as soon as you start treating these objects as data (like putting them into a matrix), you're likely going to want vectorized operations over them, which means formalized vector and matrix classes. S4Vectors in Bioconductor facilitates this for vectors, but not for higher-order arrays.

To do this in C, it would probably be easier and faster to just do the string manipulation directly. Luckily, there are already packages that have done this for you. See an example below using the S4Vectors package. foo2 <- function(mymat, colnms, tilde=FALSE) { chars <- colnms[col(mymat)] lowerChars <- if (tilde) paste0("~", chars) else tolower(chars) chars <- ifelse(mymat==1L, lowerChars, chars) keep <- mymat > 0L charList <- split(chars[keep], row...

Dear R-devs, Below is a small example of what I am trying to achieve, that is trivial in R and I would like to learn how to do in C, for very large matrices: > (mymat <- matrix(c(1,0,0,2,2,1), nrow = 2)) [,1] [,2] [,3] [1,] 1 0 2 [2,] 0 2 1 And I would like to produce: [1] "a*C" "B*c" Which can be trivially done in R via something like: foo

Hi all, Is there a better to way to subset the ROWs (in the sense of NROW) of an vector, matrix, data frame or array than this? subset_ROW <- function(x, i) { nd <- length(dim(x)) if (nd <= 1L) { x[i] } else { dims <- rep(list(quote(expr = )), nd - 1L) do.call(`[`, c(list(quote(x), quote(i)), dims, list(drop = FALSE))) } } subset_ROW(1:10, 4:6) #> [1] 4 5 6

What other packages do you have loaded? Perhaps a BioConductor one that loads S4Vectors that announces upon load: Creating a generic function for 'nchar' from package 'base' in package 'S4Vectors' Maybe a red herring... ~Malcolm > -----Original Message----- > From: R-devel [mailto:r-devel-bounces at r-project.org] On Behalf Of Duncan > Murdoch...

I recently got a request to add head() and tail() methods for Surv objects, which is quite reasonable, but not unlike other requests for logLik,? vcov, extractAIC, ...?? What they all have in common is that are methods added since creation of the survival package, and that I didn't know they existed. To try and get ahead of the curve, is there a way to list names of all of the default

Hi all, this question has already been posted on stackoverflow, however without success, see also http://stackoverflow.com/questions/27886535/proper-way-to-use-cbind-rbind-with-s4-classes-in-package. I have written a package using S4 classes and would like to use the functions rbind, cbind with these defined classes. Since it does not seem to be possible to define rbind and cbind directly as S4

Hi Kylie, Is it a list with only numerics in it? (I only see REALSXPs there, but obviously inspect isn't showing all of them). If so, you could load it up into one big vector and then also keep partitioning information around. Bioconductor does this (see ?IRanges::CompressedList ). The potential benefit here being that the underlying large vector could then be a big out-of-memory altrep. How

I can work on this.
