Dear People, I wrote the following bit of C code and (along with other bits) called it mycode.c, and compiled the file into a shared library to load into R, using R CMD SHLIB mycode.c. This was Ok, but when I tried to load this into R using dyn.load("mycode.so") I got the error > dyn.load("mycode.so") Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to

Hey, I don;t know if anyone has come across this error before... I am running R on the terminal of my MAC OS X 10.3.4 and I have written C code and compiled it using R CMD SHLIB mycode.c There were no problems in compiling so I now have mycode.o and mycode.so. I used dyn.load("mycode.so") and again, no problems. But when I try to use the code .C("mycode",x)

a) you need to read the help pages on the paste function... more likely you are looking for the paste0 function because extra spaces will most likely break the GET request format. b) quotes do not become "stuck" as \" ... that is a visual representation intended to clarify that that quote is not terminating the string but is actually part of it. If you want to see the contents

hi all - i have a source package i'm writing that i'd like to be able to install with a special library that my R src files rely on. to be more precise, i have a normal R package directory structure (i.e. src/ R/ man/ DESCRIPTION NAMESPACE etc.). i also have another directory here called depPkg, and it has it's own configure file for the canonical './configure && make

Thank you for your help in advance. I am trying to pull some data back from a web service library(httr) sample2 <- GET("https://elevation.mapzen.com/height?json={\"range\":false,\"shape\":[{\"lat\":40.7,\"lon\":-76.5}]}&api_key=mycode") result2 <- content(sample2) height <- result2$height[[1]] I would like to put by own latitude

Hi, I am now using R to implement a stepwise algrithom which includes a recursion function. e.g: -------------------------------- a = 1 *f_recursion* = function(id) { b = a + id; #: row A if (...){ a = a +1;* f_recursion*(b) } #: row B else{ .... } } ---------------------------------- I find that if the code '*f_recursion*(b)' in row B is invoked, that means

I have tried to invoke a transformation/optimization pass using -mllvm, without success. I might be missing something. For example I have a shared/dynamic library which contains LLVM passes. I used to invoke them with llvmc like this: >>*llvmc mycode.c -o mycode.o -c -opt -Wo,=-load,libFoo.dylib,-Foo* Can this style of optimization be executed using -mllvm argument? Thx, PMon On Sun,

Dear All, I have a database of 200 observations named myD. In the dataframe there are a column named code (with codes varying from 1 to 77), a column named "prevalence" with some quantitative measurements are given and an column named Pr_mean, with no values. I would like to set a cycle to compute the average of prevalence values for each different code and store the averages under the

Hi, Has anyone come across this difficulty using R-2.2.1 in Windows XP: when I try to run R CMD SHLIB mycode.c I get the response: "The system cannot execute the specified program." I've tried installing all windows updates, reinstalling R and putting "R-2.2.1\bin" at the head of my path. Googling that error message leads to lots of stuff about *.manifest files. The

Hi, I'm running long code in Batch mode (as a process in ubuntu using $nohup R CMD BATCH MyCode.R out.out &), but every one in a while it fail and the process stops. When the code finish with no problems, it sends an e-mail, but if fails, I'm not aware unless I check the working process, and I cannot be checking the process all day!. Is there any way to send me a warning when the

Hi, All: I had some trouble debugging C source dynamically loaded into R , when I issued N in gdb(or insight) , the debugger, instead of moving downward step by step, jumped to strange positions (upward, downward, one step, a few steps away). To enter the debugger, I issued gdb(insight) Rgui.exe in Cygwin and add this line : asm("int $3"); to my C code. After entering R, I

Hi There, I looked at the ZFS admin guide in attempt to find a way to leverage ZFS capabilities (storage pool, mirroring, dynamic stripping, etc.) for Xen domU file systems that are not ZFS. Couldn''t find an answer whether ZFS could be used only as a "regular" volume manager to create logical volumes for UFS or even a Linux ext2fs, with ideally, the ability to create

A major problem with the queue spinlock patch is its performance at low contention level (2-4 contending tasks) where it is slower than the corresponding ticket spinlock code path. The following table shows the execution time (in ms) of a micro-benchmark where 5M iterations of the lock/unlock cycles were run on a 10-core Westere-EX CPU with 2 different types loads - standalone (lock and protected

I have a table of workers: there are parameters of: `admin_mail`, `task` and `done`. in my `index.html.erb`, you can see the table is divided by two conditions: the first one is called `TODO TASKS'' that contains all the tasks that `done = false''. and the second one is called `DONE TASKS` that contains all the tasks that `done = true''. I used `best_in_place` in order

No. You cannot add additional passes this way, only pass 'ordinary' arguments. -- With best regards, Anton

Thanks, but I'm not sure I understand. I see no such flag in clang 2.9 nor couldn't I find any mention of it. What does it do?

Is there a similar mechanism anywhere for clang?
