Re: [R] [ADMB Users] R2admb compile problem

Hello guys Arni, you were correct. The R search path contained 'C:/MinGW/bin;' which contains a g++ compiler. I removed it and now it works fine! Thank you for the help. Just for completeness sake: (the R code and output is included below) #==

[R] R2admb compile problem

Good morning all I am trying to use R2admb and have the following very simple example. The *.tpl is included below. I am a Windows 7 user, using R3.01. //Function1.tpl //* PARAMETER_SECTION init_number x; objective_function_value C; PROCEDURE_SECTION C= pow(x

[R] R: mpirun .C and R

hello all i am busy testing some code that will be used for parallel computations on a Moab cluster. I have written a C++ program and am linking it with R using the .C command - this works correctly. Extracts of the r code (as well as the *.sh file) is included below. I am able to run the co

[R] linking r and C

some kind of metropolis hastings step} some other stuf assuming that one is unable to vectorise the R code, does it make sense to write C code to do all of the above steps? how dramatic will the time saved be? (any ideas) regards Allan Clark Lecturer in Statistical Sciences

[R] nls and "plinear" algorithm

hello all i havnt had a chance to read through the references provided for the "nls" function (since the libraries are closed now). can anyone shed some light on how the "plinear" algorithm works? also, how are the fitted values obtained? also, WHAT DOES THE ".lin" below REPRESENT? thanking you
