Dear list, I am trying to embed R into a C++ program. After some tinkering, reading the documentation and browsing the source code I have this more or less working. A very very condensed and very simplified version of the code is included below. The program can create plots. However, after the plot is initially drawn it is no longer updated. When scaling or updating the plot the window becomes

I'm trying to follow the example in the R for Windows FAQ on running gdb and am getting stuck because gdb tells me "Cannot access memory at address ...".

Hello, I'm evaluating this expression expression({ for(x in 1:5){ .Call('rh_status','x') }}) a million times from a program with R embedded in it.

Hello, I am very new to R but my question is with respect to the C API for working with an embedded R console. I have been able to start and stop an embedded R console from within a C program as well as use the API to execute commands in it. I am seeking a mechanism to individually send native R commands to an embedded console and then consume the output of these commands. Specifically, I

Hi, trying to connect a domU machine to a Win2000 AD as a member Server (with samba). Everything is OK.

Hi I try to develop a R interface to a set of C routines, in order to produce a R-package on Geostatistics. My C-code uses interaction with the user as I use printf and gets statements. I develop the code in a LINUX environment and do not face any problem having the questions and answers routed on my current Terminal. When I tried to port the package on Windows, the problems began. No message

Dear All, I've read the manual on "Writing R Extensions" and in particular the part on calling R from C. (Most of the manual is about calling C from R, not the other way around.) The good news is that I can now call _some_ R from C, specifically the R functions which have C header files. However it isn't clear to me how to call R functions that are written in R. I

I can remove the /var/locl/subsys/winbindd file to clear the subsys locked message but this does not chnage the winbind crash problem. I originally noticed this problem on 20a and thought that 20b had a fix for the winbind crash. Any clues? I am running RH ES 4.0 64 bit with samba packages downlaoded from enterprisesamba.com. PC

Hi All, I want to "merge" two datasets by column "ID" and I don't want the result to be sorted by "ID". I am doing the following: > z = merge(x, y, by = "ID", sort=F) The result is not sorted by "ID". But (as oppose to what I expected) it is not even in the original order of either "x" or "y". Can

Hi R, I have an excel file in which the third column is "date" and others are "character" and "numeric". Number of columns are 12 If I use this to read the file in R: x = read.xls("D:\\file.xls") The problem is that my date column is read in julian dates. So I am using: x = read.xls("D:\\file.xls",

I am using the library(bigmemory) to handle large datasets, say 1 GB, and facing following problems. Any hints from anybody can be helpful. _Problem-1: _ I am using "read.big.matrix" function to create a filebacked big matrix of my data and get the following warning: > x = read.big.matrix("/home/utkarsh.s/data.csv",header=T,type="double",shared=T,backingfile

Hello everyone, I want to import data from huge sas files with 100s of columns. The good thing is that I am only interested in a few selected columns. Is there any way to do that without loading the full dataset. I have tried two functions: (1) read.sas7bdat *[from library 'sas7bdat']*, and (2) read_sas *[from library 'haven']. *But couldn't find what I am looking for. Best

Hi All, I have vector of length 52, say, x=sample(30,52,replace=T). I want to sort x and split into five *nearly equal groups*. Note that the observations are repeated in x so in case of a tie I want both the observations to fall in same group. This seems a very common task to do, but still I couldn't find an R function to do this. Any help would be highly appreciated. Regards Utkarsh

Hi, With reference to the mail below, I have large datasets, coming from various different sources, which I can read into filebacked big.matrix using library bigmemory. I want to merge them all into one 'big.matrix' object. (Later, I want to run regression using library 'biglm'). I am unsuccessfully trying to do this from quite some time now. Can you please

Hi All, I ran the following lines in R: print(object.size(a <- rep(1,10^6)),units="Mb") print(object.size(a <- rep(3.542,10^6)),units="Mb") print(object.size(b <- rep("x",10^6)),units="Mb") print(object.size(b <- rep("xyzxyz xyz",10^6)),units="Mb") print(object.size(b <- 1:10^6),units="Mb") print(object.size(b

hi, the sas universal viewer might be a free, non-R way to convert a sas7bdat file to non-proprietary formats, not sure if it's windows-only. those other formats should be easier to import only a subset of columns into R.. https://support.sas.com/downloads/browse.htm?fil=&cat=74 On Thu, Aug 10, 2017 at 7:42 AM, peter dalgaard <pdalgd at gmail.com> wrote: > I had a look at this
