Hi, I need some help getting the Frontend to work - MathKernel.exe is working but when I try wine Mathematica.exe I get a lot of error messages - I'm using Mathematica Version 4.0 and wine20010824. At the end of the post there is the complete message I get from wine. Thanx a lot CFU wine Mathematica.exe For language 'german' several language ids were found: de_DE - 0407; de_CH - 0807; de...

I have some programs which were writen in mathematica or c language, but I donot know how to use these software. So I want to run them in R. Can I do it ? How to run "mathematica" or "c" programs in R? Jian Zhang [[alternative HTML version deleted]]

What are some effective ways to leverage the strengths of R and Mathematica for the analysis of a single data set? More specifically, are there any functions that can assist with any of the following? 1. Calling an R function from Mathematica. 2. Calling a Mathematica function from R. 3. Using XML or another reliable data format to pass vectors, matrices, and/or lists f...

...xtract below that was written by a leading mathematician back in 1999 when he was talking about statistics and computing. I found it interesting to share and I ask your opinion do you think this still holds today or things have changed? Thanks. ?...we would also like to mention that in our opinion Mathematica provides an excellent and indeed unparalleled environment for mathematical statistical research. In comparison, no other computing environment provides such high quality capabilities simultaneously in: symbolics, numerics, graphics, typesetting and programming. Typically most researchers need to de...

Hi all, I am an R newbie trying to do some calculations I do in Mathematica in R on a GNU/Linux system. The main thing I am interested in doing is taking a 0.999 quantile on a data set in a file who's data is normally distributed, say foo.csv. e.g in Mathematica if I have something like this : a=Import["foo.csv"] b=Transpose[a][[1]] Quantile[b,0.999] In R...

Dear R-list, I try to transform a mathematica script to R. #######relevant part of the Mathematica script (* p_sv *) dd = NN (DsD - DD^2); lownum = NN (L-DD)^2; upnum = NN (H-DD)^2; low = lownum/(2s^2); up = upnum/(2s^2); psv = NIntegrate[1/(s^NN) Exp[-dd/(2s^2)] (Gamma[1/2,0,up] + Gamma[1/2,0,low]),{s,sL,sH}, MinRecursion->3]; P...

Dear all, I have a reasonably short piece of code written in Mathematica 5.2 which I would like to convert to R. The problem is that I'm not familiar with Mathematica. I would, however, also be OK with some interface that allows me to run Mathematica from within R and use the output of the Mathematica for further analysis within R. Any advice on how to conveniently...

Hi, This question seems to be old, however I am asking it from a different point of view. R introduces itself as a 'statistical' language and environment. There are many discussions about comparing R to MATLAB or mathematica (or other similar software). It seems to me that these other software have a broader range of applications. For example, in Mathematica one can solve a partial differential equation numberically or do image processing, or, one can connect a data acquisition card to MATLAB to acquire data from a...

...tatistical distributions in R. I think the computations for the cumulative distribution function of the students t distribution in R are not very accurate. For instance, the cdf of a students t distribution with 13 degrees of freedom at 1e-4 is reported in R as "0.5000391350986764"; from Mathematica, it seems the correct value is "0.50003913510150055", only about 9 accurate digits reported in R. I also did the following from within R: ------------- df<-seq(1,100,by=1) y<-pt(1e-4,df) z<-c(0.50003183098839799,0.50003535533895194,0.50003675525997071,0.50003749999985481,0.5000...

Dear R-list members, I have a problem with translating a mathematica script into R. The whole script is at the end of the email (with initial values for easy reproduction) and can be pasted directly into R. The problematic part (which is included below of course) is <--- Original Mathematica ---> (* p_svbar *) UiA = Ni (Dsi - 2Di A + A^2)/2; UiiA = Nii (D...

I just tried rendering a plot of 166 data point (time series) on my PPC mac, and compared it with the same data rendered by Mathematica. The R plotting is very slow to paint and repaint, compared to Mathematica. This also makes it extremely awkward to use in other documentation such as pdfLatex. On closer inspection, it looks like the Mathematica plot is just a polyline, while in R it is a B-spline with each marker consisting o...

Hello, Is there some equivalent function in R of Mathematica's "Apply" i.e. Apply[ f, g[a,b]] ==> f[a,b] In concret, I have a matrix of indexes: > ind = cbind(1:5, 1:5+5) > ind [,1] [,2] [1,] 1 6 [2,] 2 7 [3,] 3 8 [4,] 4 9 [5,] 5 10 and I'd like to extract sequences 1:6, 2:7, 3:8, ..., 5:1...

Dear All, I just read an announcement saying that Mathematica is launching a version working with Nvidia GPUs. It is claimed that it'd make it ~10-100x faster! http://www.physorg.com/news146247669.html I was wondering if you are aware of any development going into this direction with R? Thanks for sharing your thoughts, Best wishes, Emmanuel

...quence of inputs that took place during the session, so that I can play them back later, and not only be left in the same state I was at the time of saving the session, but be able to see the entire history of the session (inputs and outputs). (This is somewhat reminiscent of what can be done with Mathematica notebooks, although not exactly, since, with Mathematica notebooks, one doesn't necessarily save the original inputs.) Does anyone know how to achieve this? Thanks! Roy

Hello I am trying to evaluate an Incomplete gamma function in R. Library Zipfr gives the Igamma function. From Mathematica, I have: "Gamma[a, z] is the incomplete gamma function." In[16]: Gamma[9,11.1] Out[16]: 9000.5 Trying the same in R, I get > Igamma(9,11.1) [1] 31319.5 OR > Igamma(11.1,9) [1] 1300998 I know I have to understand the theory and the math behind it rather than just ask for help, b...

Dear David, > I managed to install Sage on Windows (via a Linux VM), but I cannot find any documentation on how to use R from Sage. Maybe I > should use the web interface of Sage to avoid having to install R on the VM. In the Sage command line, you can type sage: r? to get some very basic info, and sage: r.[tab] to get various commands. This part of the interface still needs some
