mle2(): logarithm of negative pdfs
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

Control parameter of the optim( ): parscale
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

Is it possible to increase MAX_NUM_DLLS in future R releases?
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

Dynamic load library problem using R 4.0.0
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?

Using .onUnload() to unload compiled code
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,

Using dll with Visual Studio Compiler
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

Optim() violates constraints
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

call fortran in R
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:

Calling Windows DLL using .C; function name not known but in exports.
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

Include C++ DLL, error in ...: C symbol name not in load table
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];
}

Problem with dyn.load...or else...
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.

rgl crash on windows 7
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:

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,

Ferret with IMAP dirs
I''d like to use ferret to build an imap indexer and search utility, but

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.

[LLVMdev] vmkit build problems
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,

I'm trying to write a simple bash script that will cp a configuration file

with some strange output I'd like to suppress):

Request: Increasing MAX_NUM_DLLS in Rdynload.c
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
