Dear mac folks, I have started porting a large legacy toolset maintained in windows and heavily mpi laden so it can be used across platforms in R... so I am building a package out of it. On this note, I am noticing that almost all of the mpi dependent packages do not compile on the CRAN repositories.... with the basic issue that it appears it can not find mpi installed: configure: error:

Hi everybody, I'm trying to develop an R package with Fortran and OpenMP. I wrote a simple hello world but I'm not able to set the number of threads. I found this old email chain <http://r.789695.n4.nabble.com/Set-the-number-of-threads-using-openmp-with-C-td2284685.html> and I tried to set my compile instructions accordingly but i had no luck. *This is my makevars:*

I got this to work on Linux but it is not working on Windows. *My understanding is that this should also work on windows, is that correct?* If so, what should I do? differently? To get it to work on Linux, I modified my R script as follows: #' OpenMP Hello World #' #' @param nthreads The number of threads that you want to use #' @example #' hello(nthreads=2) #' @export

I have a dataframe concerning manner of death from death certificates, from 2005 to 2009 inclusive, with the following structure: > str(MannerYoung.plot.data) 'data.frame': 245 obs. of 4 variables: $ year : Factor w/ 5 levels "2005","2006",..: 1 2 3 4 5 1 2 3 4 5 ... $ manner : Factor w/ 7 levels "Accident","Homicide",..: 1 1 1

Can somebody remember me which is the command to erase columns from a data frame? Thanks Michele ___________________________________ http://it.seriea.fantasysports.yahoo.com/

I would like to subset data from a larger dataset and generate a smaller dataset. However, I don't want to use sample() because it does it randomly. I would like to take non-random subsamples, for example, every 2nd number, or every 3rd number. Is there a procedure that does this? Thanks, Nate -- View this message in context:

Hi, I need further help with my GAMs. Most models I test are very obviously non-linear. Yet, to be on the safe side, I report the significance of the smooth (default output of mgcv's summary.gam) and confirm it deviates significantly from linearity. I do the latter by fitting a second model where the same predictor is entered without the s(), and then use anova.gam to compare the

No doubt an easy answer to this exists. I have a data frame which comprises 4 matrices and 2 vectors: year(1024,6),growth(1024,6),ycens(1024,6),gcens(1024,6),yinit(1024),ginit(1024) The names of the 26 columns get denoted as y.1 to y.6, g.1 to g.6, yc.1 to yc.6, gc.1 to gc.6, yi and gi as these are the internal names. I wish to make a subset of the data using the logical vector R1(length 1024)

Dear R-helpers, I'm stuck with a little problem that surely has an easy solution but I can't think of a way to solve it. I'd really appreciate any help you can offer me! I'll provide a small example. Given a dataframe data.txt that looks like this: ID freq Var Var_mean Ratio_mean Var_median Ratio_median Var_sum Ratio_min Var_max Ratio_max Var_min

I run Fedora 22 R package. It is build with --with-lapack \ --with-blas \ --enable-R-shlib \. As the machine will act as a server with lots of R data computing, I try to optimize my R package. At first, I installed parallel_studio_xe_2016 with a free one year licence. Then, I build a package for R with Intel MKL and compiler. This took me lots of time as it was my first .rmp build. I finally

My IT people have set up a Kubuntu box with an RWkard front end.? I have OpenBLAS set up as a shared BLAS but I'm not sure how to get R to see it.? A.3.1 of the installation docs talks about it but I'm not clear if I need a option on my startup line or if I need to find a config file.? The BLAS is is in: ? /usr/lib/openblas-base ? on my machine. Recommendations?

I’ve installed R 3.1 with the latest Fedora rpm (R-3.1.0-5.el6.x86_64.rpm) and I run into some issues with openblas. I’ve documented this with an open question on stack overflow here: http://stackoverflow.com/questions/24158372/openblas-r-3-1-and-fedora-centos-dist Basically before 3.1 I had 3.02 and I was able to install and use openblas following the instruction from official CRAN

Dear List, I am trying to build R on Fedora against a threaded openblas installed from Fedora's yum repos, or alternatively swap out libRblas.so with a threaded openblas built locally. I have installed $ yum list installed | grep openblas openblas.x86_64 0.2.11-1.fc20 @updates openblas-devel.x86_64 0.2.11-1.fc20 @updates

I'm afraid there is no official mechanism in place to do that yet. There was a proposal [1], but it was never pushed

Thanks (again) I?aki. There was a typo in my reply above. I should have said: I *can't* answer the question re USE_LOCKING=1. Those other suggestions are really helpful too; I really didn't understand what the difference was (I'm still not clear what the differences are between say openblas-openmp and openblas-openmp64), but I did get R to pass mgcv's thread safe test with both
