Hi, I have been brought back to the "R-Side" from MatLab. I have used R in graduate econometrics but only for statistics and regression (linear and nonlinear). But now I need to run general nonlinear optimization. I know about the add-in quadprog but my problem is not QP. My problem is a general nonlinear (obj funct) with linear constraints.I know about the "ms" and

Hi, Quick question on reading data. I am running simulations but want to allow the user the option to define the number of simulations. How can I have R read-in user data entered from the keyboard? Is there a difference for reading in numeric and character data? For example, I am trying to write the following in R: Enter Number of Iterations? <<<the user then enters a number say Y

Hi, I have recently started using R again (switched from MatLab) and have a question regarding programming. How can I set up a file that will run several lines of R code? For example, in Fortran and DOS this used to be done via a batch file, and in MatLab I would write the code and save it in a script file, e.g., Test.m. An example of what I am trying to do is the following:

Hi, I am trying to compile a simple program with Clang 3.3 on Linux and used -pg and -O2 option. The program would crash with segfault. Interestingly if I compile it with -pg option only it works. Do you have any idea why it crashes? And any workaround? $ cat myprog.c int main() { return 0; } $ clang -v -pg -O2 myprog.c clang version 3.3 (tags/RELEASE_33/final) Target:

Hi all, Is anyone using oprofile? I'm getting segfaults from opreport at the moment, and I'm not sure if it is opreport, or just me. In case it is something just plain daft I am doing, here is how it goes: opcontrol --reset opcontrol --setup --no-vmlinux opcontrol --start ... now I run my program, /tmp/myprog ... opcontrol --dump opcontrol --shutdown then I run, opreport -l

Hi All, FileCheck is a great tool for writing tests. However, it can be also a great tool for hiding the error cause from you, especially if a very common idiom RUN: ./myprog | FileCheck %s is used. If you need to know the output of “myprog” to figure out why your test is failing — then well, good luck, you would need to manually copy’n paste that line, run it, and then note the output.

I am trying to compile an application on a CentOS 5.0 64-bit machine that gives me the error: /usr/local/bin/myprog: /usr/lib64/libstdc++: version `GLIBXX.3.4.9' not found (required by /usr/local/bin/myprog) I have gcc 4.2.3. I've performed a yum install compat-* and glibc* What am I missing? Thanks. Scott

Hi, I am trying the lattice graphics in R. Let's say, such a little experiment in file myprog.r: f <- function(){ x <- 1:10 y <- x^2 xyplot(y ~ x) } f() Then I run the program: > source("myprog.r") but nothing happens. Manully run f() at the command line: > f() then the figure is shown. This seems to be a bug only associated with lattice graphics, the

Hello. I've made out a Debian package out of Maxence Guesdon's OCaml/R bindings: http://yziquel.homelinux.org/topos/debian-ocamlr.html http://yziquel.homelinux.org/debian/pool/main/o/ocaml-r/ The upstream software itself is on the following page: http://home.gna.org/ocaml-r/ This binding is dynamically linked to the /usr/lib/R/lib/libR.so and to the /usr/lib/libRmath.so libraries.

I need to schedule a process/program every hour on the hour between 9am and 4pm on the 2nd through the 9th of each month except on Saturday and Sunday.? So, I tried this entry: 0 9-16 2-9 * 1-5 ./myprog.sh Unfortunately it runs outside of the 2nd through the 9th and still runs on Sat. through Sun. Is there a way to do this (outside the program itself)? -Frank

I am getting this error message when I try to run Rcmd SHLIB myprog.c. There appears to be a missing / between etc and i386 in the path. I am on Windows Vista and am using R version 2.12.1 Patched (2010-12-16 r53864) and just downloaded Rtools 2.12 today. Is this a bug in R? How can I resolve this? C:\tmp2>Rcmd SHLIB myprog.c cygwin warning: MS-DOS style path detected:

I understand that it is applied automatically when needed, but there are times when one would want to run it manually. An example is when I want to literally create a new wine prefix such as env WINEPREFIX="/home/bamm/apps/myprog" wineprefixcreate to prepare a clean profile for future installation of myprog. I know that running setup with a WINEPREFIX would create the clean profile,

Is this on both EL6 and EL7? If only EL7, it could be control groups causing the issue. The idea of cgroups is to prevent zombie processes, but if you need your program to spawn another process then restart itself while the other process continues to run, you need to launch it in a different control group, or the shutdown of the parent process will also kill the child. In my case, we have an

r-help, Is there a package available for R which allows you to export data directly to .xls, much like exportData(foo,"foo.xls","EXCEL") in S-PLUS ? If not, is anyone working on this, or thinking about working on this? I apologise in advance if this question has already been answered. Many thanks, Matthew

Hi, With older wine , to have a desktop icon of my program, I was doing, for example : wineshelllink --desktop --path /home/viny/.wine/dosdevices/c:/path/myprog.exe --link MyProg --icon myprog.xpm --workdir /home/viny/.wine/dosdevices/c:/MyProg But how to do with current wine version : wineshelllink doesn't exist anymore ? Thanks

When I try to build/install the quadprog package under R1.50 and NT4 it seems to have trouble finding blas routines. I'm currently using the generic blas routines, rather than ATLAS or some other tuned implementation: > Rcmd INSTALL d:/temp/quadrprog ... gcc --shared -s -o quadprog.dll quadprog.def quadprog.a quadprog_res.o -Lc:/a pps/rw1050/src/gnuwin32 -lg2c -lR

I forgot to attach the problem data, 'quadprog.Rdata' file, in my prior email. I want to report a following error with quadprog. The solve.QP function finds a solution to the problem below that violates the last equality constraint. I tried to solve the same problem using ipop from kernlab package and get the solution in which all equality constraints are enforced. I also tried an old

I'm fairly astute at C and R but new to parallelization. Would someone be willing to provide help in the form of a simple example that parallelizes an R function from the inside of a C routine? If so, write me back at izmirlig at mail.nih.gov Thanks!

Thank you Brian Ripley, Gardar Johannesson, and Marcel Wolbers for your prompt and friendly help! I will share any further learnings as I move through these suggestions. -Bob Abugov Brian Ripley wrote: I just use optim() on the sum of squares with non-negativity constraints.
