Dear R developers, Taking advantage of the yesterday discussion about the use of Depends/Import/Suggests/Enhances, I would like to add a related question. Let's assume, in the DESCRIPTION file of my package foo0, I have: Depends: foo1 Imports: foo2 while in the NAMESPACE file of my package I have importFrom("foo2", f2) and within my package I use the following two external

Hi the list I have package foo0 with a big dataset 'myData'. In DESCRIPTION, if I use 'LazyData: no', then I get: - when I open a R session : memory used=20 908 - when I attach 'library(foo0)' : memory used=24364 - then I load the set 'data(myData)' : memory used=39 668 If I use LazyData: yes', then I get - when I open a R session : memory used=20 908

Hi all! I played around with the LLVM LTO example(https://llvm.org/docs/LinkTimeOptimization.html#example-of-link-time-optimization), but got some questions. As the document says, the function foo4 should be removed. However, under my test, function foo4 is not removed. I have tried both gnu ld with LLVMgold.so and lld, neither of them removes function foo4. I compile and run the example as

For the llvm LTO example in the link:http://llvm.org/docs/LinkTimeOptimization.html <http://llvm.org/docs/LinkTimeOptimization.html>, I use below build commands to generate three different optimization level binary: -O0, -O1, -O2.

Dear R Helpers, I am trying to find a way to identify all the objects in my environment that are all caps and then end with .f. I can do the all caps part pretty easily, but I have tried a number of variations on the \ and can't get a recognition of that operator. As a simple example A.f<-"foo1" AA.f<-"foo2" aa.f<-"foo3" A.a<-"foo4" ls()

This is just a note/wishlist/for the record: With foo1 <- function() { res; } foo2 <- function() { for (i in c()) res <- 1; res; } foo3 <- function() { while (FALSE) res <- 1; res; } foo4 <- function() { if (FALSE) res <- 1; res; } we get: > foo1() Error in foo1() : object 'res' not found > foo2() Error in foo2() : object 'res' not

When I compile this program *$ cat vararg1-main.c typedef struct { double d; } S0; S0 g1; void foo0(int a, ...); int main(int argc, char **argv) { S0 s0 = { 2.0 }; foo0(1, s0); printf("%f\n", g1.d); * * return 0; }* with this command, *$ clang -target arm-none-linux-gnueabi-gcc -ccc-clang-archs armv7 -emit-llvm vararg1-main.c -S -o vararg1-main.ll -O3* I get this

Hi everyone, Hi ggplot users in particular, ggplot makes it very easy to plot things given their names when you use it interactively (and therefore can provide the names of the columns). qplot(x,foo,data=A) where A has columns (x,y,foo,bar) for example but I would like to use this from inside a function to which the name of the column is given. I cannot find an elegant way to make this

Dear List, I'm exploring the use of class inheritance for a package were developing. I want to try to build on existing a class, i first want to extend this a bit using a virtual class and then extend this virtual class in multiple other classes. This would be similar to bar3 in the example below. Since there are nice functions for creating an object of the first superclass i would like

Yes, I see the load is 8-byte aligned in the bit code. My question was, assuming that arguments requiring double word alignment have to be passed in even/odd registers, how does the backend know that %0 has to be passed in register r2 and r3? *tail call arm_aapcscc void (i32, ...)* @foo0(i32 1, [2 x i32] %0) nounwindt * It doesn't seem that ARM backend can figure out that "[2 x i32]

See ARMCallingConv.td:113. The alignment of the arg is checked and if it's 8-byte aligned, the proper registers are chosen. deep On Tue, Aug 7, 2012 at 1:20 AM, Akira Hatanaka <ahatanak at gmail.com> wrote: > Yes, I see the load is 8-byte aligned in the bit code. > > My question was, assuming that arguments requiring double word alignment > have to be passed in even/odd

Hi, although I've done S3 dispatching for more than a decade now, I think I managed to overlook/avoid the following pitfall when using NextMethod(): If you explicitly pass argument '...' to NextMethod(), you will effectively pass those argument twice to the "next" method! EXAMPLE: foo0 <- function(...) UseMethod("foo0"); foo1 <- function(...)

Hello, This is my first post to the help request list, so I'm going to err on the side of giving too much information. I'm working on writing a simulation in which agents will make repeated production and exchange decisions with randomly chosen partners. The idea is, all agents can produce two goods which they want to consume, they choose a value t in [0,10] which sets their production

Let's suppose I have userids and associated attributes... columns a and b a <- c(1,1,1,2,2,3,3,3,3) b <- c("a","b","c","a","d","a", "b", "e", "f") so a unique list of a would be id <- unique(a) I want a matrix like this... [,1] [,2] [,3] [1,] 3 1 2 [2,] 1 2 1 [3,]

Hi! I wonder if llvm::APFloat::toString() can be const since it should not modify the APFloat. -Jochen

Hi all, I am trying to construct a pairwise coocurrence matrix for certain terms appearing in a number of documents. For example I have the following table with binary values showing the presence or absence of a certain term in a document: term1 term2 term3 term4 term5 doc1 1 1 0 0 1 doc2 1 1 0 1 1 doc3 1 0 0 0 1 And I want to have a matrix with the number of the pairwise coocurrencies. So,

ARM backend emits different eabi build attributes based on the ISA variant the target supports or whether certain fast-math options are passed on the command line. For example, these are the attributes that have different values depending on whether -ffast-math is passed to clang: $ clang -target armv7-linux-gnueabi -ffast-math (with -ffast-math) .eabi_attribute 20, 2 @ Tag_ABI_FP_denormal

Hi Umesh, Thank you for the suggestion. I can use the "Brute force method " to narrow down the LTO wrong instructions here and there, but I still don't know why these wrong instructions are generated, and how to let Clang LTO don't generate those wrong instructions. I suspect the wrong code is caused by some LTO wrong optimization pass, so I hope to disable all optimizations in
