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...

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 AM Dun...

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(si...

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?

The Wine maintenance release 1.0.1 is now available. This is a maintenance release from the 1.0 stable branch. It contains only translation updates and small bug fixes. The source is available from the following locations: http://ibiblio.org/pub/linux/system/emulators/wine/wine-1.0.1.tar.bz2 http://prdownloads.sourceforge.net/wine/wine-1.0.1.tar.bz2 Binary packages for various

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 methods for this generic need to have the simplify argument, but if you do that, they won't work in previous versions of R. You'd like to have conditional code and documentation to de...

...;m just asking because building a tool to generate the instruction simplifier > automatically is relatively high on my TODO list and I don't want to duplicate > work :) The auto-simplifier is a very simple kind of super-optimizer. It tries to find optimizations suitable for InstructionSimplify [instsimplify]. The difference between instsimplify and instcombine is that instcombine is allowed to create new instructions while instsimplify needs to simplify expressions to already existing subexpressions present inside the existing expression. For example instsimplify can turn this (X +...

...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 ( Xi * Xj)) ) / n] Unfortunately this formula stays difficult in iterative programming, because I have to keep every element of X to calculate H. I know a computional simplified formula exists for the standard deviation (sd) that is much ea...

...i, 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 -loop-simplify automatically?

...mber of transformations on the results, eliminating redundant variables and reordering interactions to be after the main effects. This is not always the desired behaviour, because formulas are increasingly used for purposes other than specifying linear models. This the proposal is to add an option simplify= (defaulting to TRUE, for backwards compatibility) that if FALSE will skip the simplification step. That is, > update(a~b:c+b, .~.+b) # default: simplify=TRUE a ~ b + b:c > update(a~b:c+b, .~.+b, simplify=FALSE) # results are a mock-up a ~ b:c + b + b >From what I can tell, this can...
