similar to: Calling function in DLL using .C

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

In the following code routine 'initaquaphy' is defined in Fortran, and dynamically loaded into R.: test.f: subroutine initaquaphy(odeparms) external odeparms double precision pars(19) common /myparms/pars call odeparms(19, pars) return end $ R CMD SHLIB Aquaphy.f gfortran -fpic -g -O2 -c test.f -o test.o gcc -std=gnu99 -shared

Hi, When loading a package that provides the user-supplied RNG hook user_unif_rand, calling getNativeSymbolInfo("user_unif_rand") returns informations about the loaded symbol. I am using this to identify which package currently provides the RNG hook. The results are the same on windows and linux if only one library provides the hook. If one loads a second package that provides this

I can get the interactions between factors like this: > idx=c(1,3,6,9) > jdx=idx > levels(interaction(idx,jdx,lex.order=TRUE)) [1] "1.1" "1.3" "1.6" "1.9" "3.1" "3.3" "3.6" "3.9" "6.1" "6.3" "6.6" "6.9" [13] "9.1" "9.3" "9.6"

Hello. Me again. Have you tried to encode piano solo? Noticed high bitrate Opus gave? And there's also artefact at 15kHz which wasn't in the original audio. Visible with Spek program. Download FLAC and Opus both files, new link: http://www.filedropper.com/example_3 FLAC full: 1084 kbps; FLAC solo: 465 kbps. with --bitrate 160: Opus full: 158 kbps; Opus solo: 190 kbps. Included also Spek

Reading a flat text file 138 Mbyte large into R with a combination of scan (to get the header) and read.table. After conversion of text time stamps to POSIXct and conversion of integer codes to factors I convert everything into one data frame and release the old structures containing the data by using rm(). Strangely, the rm() does not appear to reduce the used memory. I checked using

Hi, . I know you can run Windows applications using WINE (winehq.com), but has anyone tried, say, running Word or Excel VBA code/macros based on Windows run time libraries? . the thing is that in their faq (http://www.winehq.com/site/docs/wine-faq/index) they don't even mention this possibility and searching on; VBA Word, doesn't give you any hits, even though WINE does link to windows

I am trying to add 2 stdev error bars to lattice type plots: panel.ebar<-function(x,y,dy=NULL,...) { panel.xyplot(x,y,...) panel.segments(x,y-dy,x,y+dy,...) } Then: xyplot(y~x|fc,data=dat,dy=dat$dy,panel=panel.ebar) This adds error bars but they are not conditioned on the factor fc. xyplot(y+I(y-dy)+I(y+dy)~x|fc,data=dat) This produces 3 series of points in different colors, conditioned

plot.ts has an argument yax.flip, plot.zoo does not. Is there a way to make the yaxis flip in plot.zoo? I tried using a custom panel function: panel.yaxis<-function(...) { npnl<-parent.frame$panel.number if (npnl %% 2 == 0) { axis(side=3) } else { axis(side=2) } } This leads to a blank window. I am stuck with the intricacies of the plotting and axis

In the odesolve routine lsoda(), I allow the function (named func) that calculates the system of differential equations to be defined in a dll that has been dynamically loaded from the file named in dllname. I use getNativeSymbolInfo(func, dllname)$address to get the address of the function and pass it to a C function called via the .Call interface. Inside that C function, I use

I have an R file R_test.R saved in C:\R_test folder. The R_test.R looks like this: setwd("C:/R_test") rnorm(100) write(rnorm(100),"data.txt") q(save="no", runLast = F) Next I would like use an Excel VBA/macro Shell() function to call R and execute R_test.R file. The syntax is *Shell(pathname*[*,windowstyle*]*)* I wrote an Excel macro RunRcode like this: Sub

Dear Wine-experts, I've tested the functionality of simple CUI-applications with wineconsole (Wine-0.9.50, Ubuntu 7.10). Somewhat surprisingly, there seems to be numerous major flaws in the current implementation. The best (worst?) example is the widely distributed sample code ("Console: Demonstration of the Console Functions") available in the MSDN library

I read records using scan: dat<-data.frame(scan(file="KDA.csv",what=list(t="%m/%d/%y %H:%M",f=0,p=0,d=0,o=0,s=0,a=0,l=0,c=0),skip=2,sep=",",nmax=np,flush=TRUE,na.strings=c("I/OTimeout","ArcOff-line"))) which results in: > dat[1:5,] t f p d o s a l c 1 1/21/09 5:01 16151 8.2 76 30 282 1060 53 7 2 1/21/09 5:02

Hi, I often work with R by writing long(ish) Excel-VBA macros interspersed with calls to R via RExcel. A typical example of this would be: Sub VBAMacro() 'fetch some data from an excel sheet 'do some basic stuff on said data 'transfer data from vba to R 'run some R statements 'get data back to vba 'show results on the excel sheet 'clean R by deleting all vars

Buenos días: ¿Hay alguna forma de conectar VBA de Excel con R, de forma que desde Excel se puedan cursar instrucciones de R?, ¿ y V.Basic con R? Gracias anticipadas. Saludos [[alternative HTML version deleted]]

Hi, I am very new to R so please excuse me if I am asking very obvious questions. I am trying to call a blackbox api function implemented in as a COM object from R. The function definition says that 1. if calling from VBA, the first parameter should be set to "Nothing" 2. if calling from matlab, the first parameter should be set to [] What should be the equivalent for above in R?.

Hi, I am running a test to call an R script with in excel using VBA. My VBA code is shown bellow. The middle section of this mail also includes the content of my Rscript. The bottom part shows the error message form the R console. It seems that Excel is opening the R console without any problems. The problem I am seeing is that Rinterface.RRun instruction is interpreting the "\T"

Please, help with announcing an error from Rterm: I am calling R from an Excel VBA and noticed that if there is an error nothing conspicuous happens. I would like just a popup window when R cannot finish cleanly. The "ret " value returned from Shell is useless in determining what happened.
