Integration with an Indicator Function in R
Hi all, I have some some problem with regard to finding the integral of a function containing an indicator function. please see the code below: func1 <- function(x, mu){ (mu^2)*dnorm(x, mean = mu, sd = 1)*dgamma(x, shape=2)} m1star <- function(x){ integrate(func1, lower = 0, upper = Inf,x)$val} T <- function(x){ 0.3*dnorm(x)/(0.3*dnorm(x)+0.7*m1star(x))} func2 <-

Is there a way to source from a specific Git repository without hardcoding the location everywhere?
Folks, A small group of us are working together to develop a set of R functions to support data management and analysis using Eclipse/StatET in a Windows environment. We are using Git/EGit for version control. We work within our own repository and occasionally push to a common remote location. I'd like to have the code source files from the 'local' git repository without

plotting 3 functions on same graph
hi all, I wish to draw on the same graphic device 3 functions. But i don't want them to be on different graph, i want to compare them on the same I don't need mfrow or mfcol, I need something else... 1 graph on 1 device inside this graph 3 ploted function. I saw something unsing data.frame, but i think it's overkill, and something less complicated must exist, if not why? why not

: global and local variables
Hi all I have a problem pertaining to local and global variables. Say I have a function defined as follows: a<-function(x) {y<x^2} i.e a(2) [1] 4 function b is now defined to take the value of y and do some manipulation with it. As it stands I dont know how to store the variable y such that other functions are able to reference its value. I know that I

[LLVMdev] JIT'ing 2 functions with inter-dependencies
I am having problems JIT'ing 2 functions where one of them calls the other. (I am using the old JIT interface). Here is the setup: define void @func1() { entrypoint: call void @func2(void) ret void } define void @func2(void) { entrypoint: ret void } (I omit the arguments and function bodies for simplicity.) It's 'func1' that would be called from host code,

Generalizing call to function
Hello guys, I would like to ask for help to understand what is going on in "func2". My plan is to generalize "func1", so that are expected same results in "func2" as in "func1". Executing "func1" returns... 0.25 with absolute error < 8.4e-05 But for "func2" I get... Error in dpois(1, 0.1, 23.3065168689948, 0.000429064542600244,

[LLVMdev] LLVM IR for inline functions
Hi, I have a naive question on how to generate LLVM IR for inline functions. I have compiled this C code: *inline void func1()* * {* * int x=3;* * }* * void func2()* * {* * func1();* * int y = 4;* * }* into LLVM IR, using clang -emit-llvm -S -c <filename> But the generated LLVM IR file does *not* have func1() expanded (see below for the relevant parts). *; Function Attrs: nounwind

[LLVMdev] How to split module?
Hi, all. My question is about how to split one module into N modules(N >= 2)? For example, given the following code: #src.c# int main() { //......// func1(); func2(); //......// return 0; } void func1() { //......// } void func2() { //......// } func1() has no dependence with func2(), so they can perform parallel execution. And I have to split src.c into src1.c

reusing external functions across libs
Hi, I am searching for a way to solve the following problem: I want to use an external function, defined in a dyn.load()ed shared object, in another dyn.load()ed shared object. Currently I have to take the sources (Fortran) from one libraries src/ directory and copy them into the src/ dir of the other library, resulting in two copies of this function. This is bad for maintanance and maybe also

Communicating from one function to another
My question is a seemingly simple one. I have a bunch of user-defined functions which compute such-and-such objects. I want to be able to define a variable in a particular function, then make use of it later, perhaps in a different function, without necessarily having to move it around in argument lists. In the C community, it would be called a "global" variable. Question 1: Is this

Questions for package ts prediction
Dear helpers, I am trying to write a function to return prediction values using package ts. I have written three different versions since I am not sure what's wrong with my func2. func and func1 return the same results.But func1 and func2 don't. In particular, the only difference between "func1" and "func2" is the function variable name being y and data, respectively.

Getting names of objects passed with "..."

LLVM EH tables much larger than GCC's
Hi, I'm investigating the size of Clang's generated binaries relative to GCC, when targeting Android, and I've noticed that Clang's exception tables are much larger -- the .ARM.extab section is about 2.5 times as large in two examples. I noticed a couple of differences between Clang and GCC: 1. *ULEB128 encoding.* In the call site table, GCC encodes offsets using a ULEB128

[LLVMdev] Determining the base offset of the stack for a function.
I am running into an issue where if I have multiple functions compiled in the same compilation unit the stack offset is not starting at zero. For example: func1(...) { ... } func2(...) { ... } Say the first function uses 64 bytes of the stack and an assumed offset of 0 and the second function uses 32 bytes of the stack but an assumed offset of 64. I've found out how to get the
