search for: array

Dear List A 2-dimensional array seems to be "interpreted" as a matrix whereas higher dimensional arrays are interpreted as arrays, e.g. > a1 <- array(1:8,c(2,2,2)) > class(a1) [1] "array" > a2 <- array(1:4,c(2,2)) > class(a2) [1] "matrix" If I write a generic function (apologies...

We have a test that looks like this… define void @array16_store() { ; CHECK-LABEL: array16_store: ; CHECK: ldi [[REG1:r[0-9]+]], 204 ; CHECK: ldi [[REG2:r[0-9]+]], 170 ; CHECK: sts int.array+3, [[REG2]] ; CHECK: sts int.array+2, [[REG1]] ; CHECK: ldi [[REG1:r[0-9]+]], 187 ; CHECK: ldi [[REG2:r[0-9]+]], 170 ; CHECK: sts int.array+1, [[REG2]] ; CHECK: s...

...roblem I don't know how to solve. Therefore, I hope someone can provide me with the information or pointers I need in order to understand the way in which the communication between R and C occurs. I have the following C code which basicallly reflects what I want: typedef struct { float *array; size_t used; size_t size; } Array; void main2R() { Array a; examplefunction(&a); /*fills and dynamically grows a->array*/ } Now I would want to return a.array or a->array to R. According to the R manuals, the compiled C code should not return anything except...

Hi all, I am having a bit of trouble with the array structure of R. What I want to do is dynamically add/remove elements to an array. For example: Let's say I have created an array: > myArray <- array(c(3,8), dim=c(1,2)) > myArray [,1] [,2] [1,] 3 8 And I now want to, for example, push an element (5,6) on to this array...

I'm running up against an error with this IR: %array$str = type { i64, [0 x %str] } %array.raw = call i8* @malloc(i64 %objsz) %array = bitcast i8* %array.raw to %array$str* %array.data = getelementptr %array$str* %array, i32 0, i32 1 This is kind of hand-written, but it errors out, like this: print-var.ll:50:30: error: invalid getelementptr indices...

Hi All, I was wondering if there is an optimisation pass that moves a stack allocated array, initialised with constant values, to a global constant array. And if there is such a pass, what requirements are there for it to operate? My optimised IR is below. As you can see an array of 5 integers is created with alloca, then each element is stored to in turn. It would be nice if this ar...

...te a simple problem but I'm having troubles on how to solve it, I've read tons of old mails in the archives and looked at some slides from?Deepayan Sarkar but still can not get the point. This is the context. I've got data on 9 microRNAs, each miRNA has been measured on three different arrays and on each array I have 4 replicates for each miRNA, which sums up to a total of 108 measurements. I've the suspect that measurement on the first array are systematically lower than the others so I wanted to draw some line plot where each panel correspond to a miRNA, and each line correspond...

Hi, I would like to know how to locate an LLVM instruction in the source code, i.e. to get the line number of its corresponding source code statement. I remember in LLVM 2.4, DbgStopPointInst is designed to help this locating, but it seems deprecated in the latest LLVM.

I'm not enthusiastic about matrices extending arrays. If a matrix is an array, then shouldn't all vectors in R, be arrays too? > #mockup > cla...

...la-element but more elemental)? Perhaps my idea to solve my problem is a little bit strange. My general problem is, that I have to do arithmetics for which there seems to be no function available that I can apply in order to be more flexible. To be precise, I have to add up three dimensional arrays. I can do that like this (as someone suggested on this help-list ? thanks for that!): (array[,,1] + array[,,2] + array[,,3]) / 3 However in my case it can happen that at some point, I don't have to add 3 but 8 'array-slices' (or 10 or x). And I don't want to manually expand th...

...vel ... but I would like to fix a few things. Hopefully the following is a sufficiently "small, self-contained example" (though it has 2 side questions injected--answers to those are appreciated also): # start example library(reshape2) library(lattice) lon=11 lat=7 lev=5 len=lon*lat*lev array.3d <- array(data=c(1:len), dim=c(lat, lon, lev)) # Rewrite the array values "more spatially," i.e., row-wise from # bottom left. If there's a more-R-ish way to fill this array # as specified, please let me know: I know 'for' loops are deprecated # in R. i=1 for (z in 1:le...

Is it possible to print the before the instructions as comment? For example: array.c: ------------------------------ int array[5] = { 1, 2, 3, 4, 5 }; int main () { array[1] = 5; array[4] = array[1] + array[3]; array[0] = array[4] * array[1]; array[2] = array[0] + 1; return array[2]; } ------------------------------ $ clang -emit-llvm -O1...

The VMCI handle array has an integer overflow in vmci_handle_arr_append_entry when it tries to expand the array. This can be triggered from a guest, since the doorbell link hypercall doesn't impose a limit on the number of doorbell handles that a VM can create in the hypervisor, and these handles are stored in a han...

Dear R users, I want to calculate the bias and variance of an estimator for several values of two parameters a and b. For example : b1 b2 a1 bias bias variance variance a2 bias bias variance variance Can one do array of arrays ? I have tried and it did not work. Actually I would like to get this array for several values of the number of observations. That would be an array of arrays of arrays :-) Maybe there is a better way to do that... Is there also a way to export arrays to Latex ? Thank you very much...

Fake flexible arrays (zero-length and one-element arrays) are deprecated, and should be replaced by flexible-array members. So, replace zero-length array with a flexible-array member in `struct PACKED_REGISTRY_TABLE`. Also annotate array `entries` with `__counted_by()` to prepare for the coming implementation by GCC...

..., you get NULL rather than [1] k. Is this logical? Here's the way I explain it (and maybe someone can provide a more accurate explanation of what's going on): R has several types of scalar (atomic) values, the most common of which are numeric, integer, logical, and character values. Arrays are data structures which hold only one type of atomic value. Arrays can be one-dimensional (vectors), two-dimensional (matrices), or n-dimensional. (We generally use arrays of n-1 dimensions to populate n-dimensional arrays -- thus, we generally use vectors to populate matrices, and matrice...

Hello, We would like to begin discussions around a new set of intrinsics, to better express multi-dimensional array indexing within LLVM. The motivations and a possible design are sketched out below.

Hi, all! I have a story steps array.rb and the story array.story. I can run it with ruby array.rb But when I execute spec array.rb nothing happened. I''m wondering how can I use spec command to execute stories? (executing examples is OK) Or maybe another question. If I have to run stories with `ruby'' command,...
