Dear All: The question: How do I check for existance of the GUI, instead of checking the variable of the GUI? I created a log window for several applications, they will check for the existance of log window, if it...

Hi, I am writing a function in C that is meant to be called by R. In the C function, I used a gsl function gsl_stats_mean. The code is as simple as below void gsl(double *m, int...

Hello, I recently received an email regarding an error for DSS: https://bioconductor.org/checkResults/3.15/bioc-LATEST/DSS/palomino3-buildsrc.html. The error is about the parallel computing in Windows. However, I have corrected this error a while...

I?m not that familiar with R?s garbage collection, but maybe you can call something manually to free up memory? > rewrite your program to work more incrementally and releasing memory as needed. Or the simple alternative solution is to...

Hi, I have a matrix with positive numbers, negative numbers, and NAs. An example of the matrix is as follows -1 -1 2 NA 3 3 -2 -1 1 1 NA -2 I need to compute a scaled version of...

Hi all: I'm working on a project that I have packaged for ease of distribution. The different simulations in the package share code, so obviously I have those parts organized as functions. Now, I want to show people my...

It is related to MPI_INITIALIZE and MPI_FINALIZE. Either one can only be called once. Hence once detach() is used, R is no longer to be a MPI aware process and cannot be a MPI process again. Hao Blanchette...

Hello, I am trying to do some contrasts using a mixed model, but don?t know how to use it in lme4. I've done the multiple contrast, but I believe the power of this method is lower than ideal...

Rick, I noticed you were using mpicc. If mpicc is from /usr/lib64/openmpi/1.2.7-gcc, then it knows where to find mpi.h and other header files. Maybe mpicc is not setting properly and it appends mpi...

You can read the manual below. good luck! http://www.biometrics.mtu.edu/CRAN/doc/manuals/R-exts.html#The-R-API For example, suppose we want to call R's normal random numbers from FORTRAN. We need a C...

Hi Luis, I recall having this problem, and I, too, had solved it by creating .Rd files for the c++ class objects. I don't have this error anymore, and I believe the main difference is that I am curating...

Hi, All: I am having a problem with handling global variable value in GUI programming, I hope R gurus can give me some advice on it. What I want to do is to read in a dataset, display some information...

Hi Everyone, I encountered an issue during my submission of my package (see original message below). I ran checks and tests with testthat::test_dir("tests/") and devtoos::check(), and all seemed fine except some issues with undocumented objects which...

The first argument of mpi.parLapply is x which is mixed with your x. Change your x to a different one and your codes should work. Hao Xiaochun Sun wrote: > Hi, > > I am using Rmpi and met a problem about...
