Hi, In order to use the mle2-function, one has to define the likelihood function itself. As we know, the likelihood function is a sum of the logarithm of probability density functions (pdf). I have implemented myself the pdfs that I am using. My problem is, that the pdfs values are negative and I cann't take the logarithm of them in the log-likelihood function. So how can one take the

Hi everybody, I am using the L-BFGS-B method of the mle2() function to estimate the values of 6 parameters. mle2 uses the methods implemented in optim. As I got it from the descriptions available online, one can use the parscale parameter to tell R somehow what the values of the estimated parameters should be . . . Could somebody please help me understand what one has to do actually with the

Thanks for all your great answers. The app I?m working on is indeed an exploratory data analysis tool for gene expression, which requires a bunch of bioconductor packages. I guess for now, my best solution is to divide my app into modules and load/unload packages as the user switch from one module to another. This brought me another question: it seems that unload package with the

I'm having problems getting code that runs under 3.6.1 on MacOSX (and Ubuntu) to run the R version 4.0.0 on Windows. I have not tested R 4.0.0 on mac (yet). Key question: Has anything changed in R 4.0.0/Windows regarding how dynamically loaded libraries are accessed? Can someone please point me in the right direction? WORKS On MacOSX Under: R version 3.6.1 (2019-07-05) -- "Action of

If one wants to unload compiled code for a package containing a namespace, my understanding is that .onUnload() should be used, with a call to library.dynam.unload(). This is used in e.g., the stats and methods packages, but it appears to me that the compiled code is not being unloaded when the package is detached(). Am I misunderstanding something? Best, Jim > search() [1]

Hi, I have created a dll in Fortran and used the Visual Studio 2005 Compiler. I've read that certain problems can arise based on the compiler used and that these problems can sometimes cause R not to be able to access everything appropriately, but I've not found how to fix any of these problems. Specifically, after using dyn.load, I know the dll has been loaded because it is listed in

Hi, I am using the mle2 method of the package 'bbmle'. The method is calling as far as I understood it the optim method "L-BFGS-B" (this is the method I use). The latter one allows the user to impose box constraints on the variables, i.e. to give lower and upper bounds. It is important that the initial values satisfy the constraints. In my problem, it is the case. I do not know

Hello, I used a mac G5, R.2.1.1, and G77 3.4.4 and I would like to use and call a fortran subroutine. The trouble is that it seems I am not able to correctly load the compiled code. Here is what I have done: In the terminal this how I compiled my fortran code: R CMD SHLIB ~/Desktop/Fortan_kmeans/kmeans3.f There is the wrapper I have paste inside de kmeans3.f file: c

First time ever that I try to call subroutines in a Win DLL using R. Have done this before using VBA and Python. The C code's function argument list contains only double pointers (double *x). The function is declared void, the output value is one of the arguments. C calling sequence is used. When inspecting the exports of the DLL with dumpbin I can see that the function I need is

Hello R experts I am googling and reading around, however, I can't get it working (perhaps because I do not understand much C, however, I'll give it a try). I am trying to include C++ code into an R routine, where the C++ code looks: #include <iostream> using namespace std; void foo (double* x, double* y, double* out) { out[0] = x[0] + y[0]; } Back in R, the command R CMD

Hi everybody, I'm working on Mac OS X and R-2.1.0 (by the way, sorry for the multiple emails last time, had a technical problem, and thanks for the constructive comments.) I have a .R function which calls a .C function. The R function's name is K_MEANSR.R and the other is K_MEANSC.C. I compile it with 'R CMD SHLIB K_MEANSC.C' in the terminal. I get both .so and .o files.

not sure if i misunderstood the documentation but my understanding is the -a option preserves ownership and permissions on transfer. i did a remote test and i see ownership changed is that becuase user does not exist in the remote box 4.0K drwxr-xr-x 14 zoe zoe 4.0K 2007-07-15 08:08 zoe but in the remote system they changed to 4.0K drwxr-x--- 8 boricua users 4.0K 2007-05-02 11:07

I have asked a similar question before but this time the problem is somewhat more involved. I have the following data: case;name;x 1;Joe;1 1;Mike;1 1;Zoe;1 2;Joe;1 2;Mike;0 2;Zoe;1 2;John;1 3;Mike;1 3;Zoe;0 3;Karl;0 I would like to count the number of "case" in which any two "name" a. both have "x=1", b. the first has "x=0" - the second has

I have a co-worker who has installed R 3.4.2 on Windows 7. When this person tries to load the rgl package with library(rgl) A dialog box appears with the message: R for windows gui frontend has stopped working I suspect a conflict problem with a dll, but I'm not sure how to identify if this is the problem since R is crashing immediately. Interestingly, when we start R and do NOT load rgl,

I''d like to use ferret to build an imap indexer and search utility, but want to check first to see if anyone else is working on this and offer my help. Anyone? Also, if you could provide any helpful pointers on indexing directories via ferret, it''ll be very much appreciated. I''m a lucene nuby. Thanks! John -- Posted via http://www.ruby-forum.com/.

Hi Zoe, Unfortunately, I don't have access to a x64 machine anymore, so I can't test that architecture on vmkit. Could you install a virtual machine on your machine that is x86_32? I know it has been successfully built and ran on x86_32 on different systems. Cheers, Nicolas On Wed, Jun 30, 2010 at 7:49 AM, Zoe Wolk <zoewolk at gmail.com> wrote: > Hi again Nicolas, > >

Thanks Henrik this is very helpful! I will try this out on our tests and see if gcDLLs() has a positive effect. mlr currently has tests broken down by learner type such as classification, regression, forecasting, clustering, etc.. There are 83 classifiers alone so even when loading and unloading across learner types we can still hit the MAX_NUM_DLLS error, meaning we'll have to break them

Hi Nicolas, No, I built llvm-gcc myself by checking it out via svn, using these instructions: http://llvm.org/docs/GCCFEBuildInstrs.html thanks -Z > Hi Zoe > (Please, try to reply to the same thread) > I think you may have an old version of llvm-gcc.

Hey guys, I'm trying to write a simple bash script that will cp a configuration file to a backup (with the date) remotely to a bunch of machines, using sudo with ssh. I notice that if I run the commands individually, they both work (albeit with some strange output I'd like to suppress): [tdunphy at MIAGRBISSH01V ~]$ ssh -q -t -t -t MIAGRBIORCA00V sudo -S 'cp -v
