The survival package, like many others, has several helper functions that are not declared in the namespace, since their only use is to be called by other "main" functions of the package.? This works well since the functions in the survival namespace can see them --- without ::: arguments --- and others don't. Until a situation I ran into this week, for which I solicit comments

Hello, I'm working with a very large dataset (250,000+ lines in its' current form) that includes presence only data on various species (which is nested within different sites and sampling dates). I need to convert this into a dataset with presence/absence for each species. For example, I would like to expand "My current data" to "Desired data": My current data

Hi all, I have a C function, say Cfun, that calls Lapack's DGEMM routine and I need to create a shared library to use Cfun inside R. The C file is the following #include<stdio.h> #include<R.h> #include<R_ext/Lapack.h> void Cfun(double *res, double *X, int *n, int *q) { char *ptr_TRANSA, TRANSA='T', *ptr_TRANSB, TRANSB='N'; ptr_TRANSA=&TRANSA;

Inthe code below I was trying to to obtain the GMM estimates for CAPM (REGRESSION) for 36 stocks each have 180 observations,however it only gives me one output rather than 36. In SAS i would just put in a *By statement*. I have a variable TICKER that categorize them into 36 groups. *How can I obtain all 36 output instead of just one.* **

Hi, I'm Ryo Ota. I'm using LLVM 3.8.1. I have a quesion about inlining function in C++ API. I'd like to inline some functions in a module in the same way as `opt -inline` command. But my C++ code didn't work what I want to do. For example, by using `opt -inline` command,`main.ll` is converted into the `inlined.ll`(`opt` command worked what I want to do) [main.ll (Not inlined)]

Hi, I tried this as well, using the following line to add function declaration to the caller module. Function::Create(FT, Function::ExternalLinkage, "gcd", mod); Where "FT" is the same as before. And the output produced by the PrintModulePass becomes: ; ModuleID = 'GCDMain' declare i32 @gcd(i32, i32) define i32 @main() { EntryBlock: %tmp = call i32 @gcd(i32

I've just begun playing around with defining functions in R and I'm not really sure what's going on in the following situation. I've defined the following function: gcd <- function(x,y) { x <- as.integer(x); y <- as.integer(y) q <- as.integer(x / y) r <- x - q * y if (r==0) y else gcd(y,r) } As expected, it gives the following results: > gcd(3,2) [1] 1

Mark, that's actually a fair statement, although your extra operator doesn't cause construction at parse time. You still call paste0(), but just add an extra layer on top of it. I also doubt that even in gigantic loops the benefit is going to be significant. Take following example: atestfun <- function(x){ y <- paste0("a very long", "string for

hi ?integer says: Note that on almost all implementations of R the range of representable integers is restricted to about +/-2*10^9: 'double's can hold much larger integers exactly. I am getting very confused as to when to use integers and when not to. In my line I need exact comparisons of large integer-valued arrays, so I often use as.integer(), but the above

This is a perfectly legal > and valid solution. Valid in a package, but forces code to call a loaded library version of a function rather than (say) a 'source'd user-space version that is under

Hi All, I have some questions regarding the R C API. Let's assume I have a function which is defined as follows: R file: myfunc <- function(a, b, ...) .External(Cfun, a, b, ...) C file: SEXP Cfun(SEXP args) { args = CDR(args); SEXP a = CAR(args); args = CDR(args); SEXP b = CAR(args); args = CDR(args); /* continue to do something with remaining arguments in "..."

Dear, I am looking at the Instructions defined in the XXXXInstrInfo.td where I can see a def record defined like below def ADD8rr : I8rr<0x0, (outs GR8:$dst), (ins GR8:$src, GR8:$src2), "add.b\t{$src2, $dst}", [(set GR8:$dst, (*add *GR8:$src, GR8:$src2)), (implicit SRW)]>; Now here I would like the to

Hello Everyone, I am trying to create two modules in LLVM, where first module contains the definition of a function, gcd in this example and another module contains a call to this function. My example is based on the following tutorial, with a few changes. http://llvm.org/releases/2.6/docs/tutorial/JITTutorial2.html When I execute the verifier pass on my modules, it complains that the

You can't reference a global in one module in another module. Either stick with

I am trying to solve an integral in R. However, I am getting an error when I am trying to solve for that integral. The equation that I am trying to solve is as follows: $$ C_m = \frac{{abs{x}}e^{2x}}{\pi^{1/2}}\int_0^t t^{-3/2}e^{-x^2/t-t}dt $$ [image: enter image description here] The code that I am using is as follows: a <- seq(from=-10, by=0.5,length=100) ## Create a function to compute

Thank you for your reply Jiefei. I think in theory your solution should work. I'll have to give them a try.

Sorry if this is too newbie. I would appreciate any help. I would like to control shell access by group so that I don't have to add it to parameter "template shell: and give everyone that is authenticated shell access. I am using winbind so I see every window user when I do a "getent passwd" with /bin/null as their shell but I don't know how to go and change that for

Hello: I have a 4-column dataset: Crime, Education, Urbanization, Age. I want to construct a multiple linear regression to find the effect of Education, Urbanization, and Age on Crime" lm(Crime ~ Education + Urbanization + Age) If I use + in above statement, does it mean it will build a model to find the relationship between Crime and Education when Urbanization and Age are held constant?
