similar to: ... (dotMethods) and cbind/rbind: how to give the signature?

The methods package ?cbind2 includes the instruction to use via methods:::bind_activation(TRUE). This changes the default definition of cbind globally, disrupting proper evaluation in packages not using cbind2. Is cbind2 a hold-over from a time when ... could not be used for dispatch? What is a safe way for a package to use cbind2? This came up in the context of complex package dependencies

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

Are you able to create a reproducible example, somehow?

As some of you may have seen / heard in the past, it is not possible to make cbind() and rbind() into proper S4 generic functions, since their first formal argument is '...'. [ BTW: S3-methods for these of course only dispatch on the first argument which is also not really satisfactory in the context of many possible matrix classes.] For this reason, after quite some discussion on

I've implemented the proposed changes in R-devel. Minimally tested, so please try it. It should delegate to r/cbind2 when there is at least one S4 argument and S3 dispatch fails (so you'll probably want to add an S3 method for your class to introduce a conflict, otherwise it will dispatch to cbind.data.frame if one of the args is a data.frame). There may no longer be a need for cBind() and

Hi Michael, I've tested your change in r67699 (using r67773) and the function now correctly dispatches to r/cbind2 within the R-session without bind_activation(TRUE). However, running unit tests using R CMD check I figured out that the same function call delegates to r/cbind.matrix (function uses S4 class as first- and matrix as second argument). Is this a bug and/or how can I get function

sorry - I just got irritated by my different R-versions. The behaviour I described in the previous mail was discovered using R 3.1.2 without bind_activation(TRUE). In r67773 all calls are delegated to r/cbind.matrix and not r/cbind2. As a workaround I have now implemented an S3 method for my S4 class which correctly dispatches for both versions (3.1.2 and r67699+) - see also the commit for the h5

Hi, I think this is a bug (even though I can't find documentation explicitly saying that it should work). Basically, Rf_PrintValue(obj) fails when 'obj' is an S4 object that should be printed using show() rather than print(). From the error message I'm guessing that the need to use show is detected correctly but then show is not found. "cbind2" in the code below is just

Hi I have some problems in defining new generic functions and classes. Just have a look at the following example: require(fPortfolio) setClass("PROBECLASS", representation( type="character" ) ) isGeneric("setType<-") #Returns TRUE #I would like to define a specific function for

Dear all, As far as I understand, the number of arguments in methods:::cbind is limited by the "self recursive" construction of the function which generates nested loops. A workaround could be to use the internal cbind function on blocks of non S4 objects. The limitation would then be reduced to the number of consecutive S4 objects. ##### R code ##### dfr <- data.frame(matrix(0,

Dear list, I have a matrix, spc, that should row-wise be interpolated: E.g. spc <- matrix (1:1e6, ncol = 250, nrow = 4000, byrow = TRUE) spc [1:10, 1:10] shifts <- seq_len (nrow (spc)) wl <- seq_len (ncol (spc)) interpolate <- function (spc.row, shift, wl) spline (wl + shift, spc.row, xout = wl, method = "natural")$y interpolate (spc [1,], shift = shifts [1], wl = wl)

Dear R-Developers, could 'sample' gain a ... argument? As a convenience function, I added a sample Method to my hyperSpec class. This function however has a flag indicating whether the results should be returned directly as a hyperSpec object or rather as indices that give a random sample. For the moment, I use SetGeneric to add the dots argument, but this of course gives a warning

Dear R users, Here is my problem: I have an array with at least four dimensions: > dim(myArray) [1] 20 17 3 6 I'd like to apply a function to each occurrence of the matrix (3x6) defined by the last two dimensions.

Dear all, I just noticed, that prompt () looses backticks that protect default arguments: f <- function (FUN = `*`) {} cat (prompt (f, NA)$usage) yields: \usage{ f(FUN = *) } %- maybe also 'usage' for other objects documented here. without the backticks, which is of course found by R CMD check as syntax error. While this is easily fixed if the .Rd is further edited manually, I
