Dear R Developers, the new simplify argument in apply causes that my package (hsdar) does not pass the checks in R-devel. The workaround, Kurt Hornik send me, is working for the R-code: if("simplify" %in% names(formals(base::apply))) do something else do something else Unfortunately, I cannot conditionalize the man pages of the functions. I get the message that

Interesting problem. I'm very rusty on S4 but would one solution be to, already now, add 'simplify = TRUE' to the S4 method and document it; setMethod("apply", signature(X = "Speclib"), function(X, FUN, bySI = NULL, ..., simplify = TRUE) { ? Henrik On Fri, May 22, 2020 at 6:26

While working with sapply, the documentation states that the simplify argument will yield a vector, matrix etc "when possible". I was curious how the code actually defined "as possible" and see this within the function if (!identical(simplify, FALSE) && length(answer)) This seems superfluous to me, in particular this part: !identical(simplify, FALSE) The preceding

Wouldn't that change how simplify='array' is handled? > str(sapply(1:3, function(x)diag(x,5,2), simplify="array")) int [1:5, 1:2, 1:3] 1 0 0 0 0 0 1 0 0 0 ... > str(sapply(1:3, function(x)diag(x,5,2), simplify=TRUE)) int [1:10, 1:3] 1 0 0 0 0 0 1 0 0 0 ... > str(sapply(1:3, function(x)diag(x,5,2), simplify=FALSE)) List of 3 $ : int [1:5, 1:2] 1 0 0 0 0 0 1 0 0

My wiki username is HoLee . Now, the simplified chinese frontpage is maintained by TimothyLee. Because of his efforts ,the Traditional Chinese Frontpages and Simplified Chinese Frontpages are created and maintained very well. I know that TimothyLee is from Taiwan,so the Simplified Chinese Frontpage is translated from Traditional Chinese Frontpage directly.So,there are some sentences is

You?re right, it sure does. My suggestion causes it to fail when simplify = ?array?

You didn't explained what the error is. This is what it looks like to me, but I'm probably wrong in some details: 1. R-devel added an argument to the apply() function, so the header has changed from function (X, MARGIN, FUN, ...) to function(X, MARGIN, FUN, ..., simplify = TRUE) 2. Your package converted the function apply() to an S4 generic. 3. Now the signatures of your

There's some interest in my "auto-simplifier", which is nice :), so let me explain a bit about it.

Dear R-ians, I'm looking for a computational simplified formula to calculate a measure for heterogeneity (let's say H ): H = sqrt [ (Si (Sj (Xi - Xj)?? ) ) /n ] where: sqrt = square root Si = summation over i (= 0 to n) Sj = summation over j (= 0 to n) Xi = element of X with index i Xj = element of X with index j I can simplify the formula to: H = sqrt [ ( 2 * n * Si (Xi) - 2 Si (Sj

Martin In terms of context of the actual problem, sapply is called millions of times because the work involves scoring individual students who took a test. A score for student A is generated and then student B and such and there are millions of students. The psychometric process of scoring students is complex and our code makes use of sapply many times for each student. The toy example used

Hi, I know when a pass needs other passes, it will use something like this: "AU.addRequired<LoopInfo>();". But this is usually used for the analysis passes. When a pass needs another transform pass, can it call it automatically? For example: Some loop optimizations may need loop-simplify, I need add -loop-simplify before calling these passes manually, or they can call the pass

Dear All, Martin Maechler has asked me to send this to R-devel for discussion after I submitted it as an enhancement request ( https://bugs.r-project.org/bugzilla/show_bug.cgi?id=17563). At this time, the update.formula() method always performs a number of transformations on the results, eliminating redundant variables and reordering interactions to be after the main effects. This is not always

I was trying the new feature you introduce about printing out the graphs, so I updated my version of llvm/clang/polly synchronizing them to the last version, but I get this error launching clang (also , I recently switched to MacOS X for development): $ clang not_so_simple_loop.c -O3 -Xclang -load -Xclang ${PATH_TO_POLLY_LIB}/LLVMPolly.dylib -mllvm -enable-polly-viewer -mllvm -enable-iv-rewrite

Hi, I have written a package that contains many s4 generic functions and associated methods. I am having a lot of trouble getting R to build the help pages for these generic functions without reporting, "missing link(s): ~~fun~~, which means that it cannot find the appropriate function when code in the example section of the help is run. Right? After some playing around I can get it to
