Looking for a recommended package that handles prime number computations. Tried the following unsuccessfully: primeFactors() in the R.basic package failed to install. primes() and primlist are broken in Schoolmath pkg on CRAN. My analysis can be found here http://j.mp/9BNI9q Not sure what the procedure is for getting things fixed, so I've cross-posted to r-dev as well. --njg

Hello, As recommended by N. Gunther, I'm writing you because I have some difficulties to create a script to track computer performance, as done in Holtman, 2005 (Visualization techniques for analysing patterns in system performance). I would like to do a leveplot, with the kind of file here enclosed. I assume I should create a matrix in R, then use the function 'image'. As I am not

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 from one environment to

Hi, this is not an R-help post, but I found this extract 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

Hi People, I have just started building my own RPMS on both Fedora and CentOS and generally things have gone well. Currently I am trying to create RPMS for some commercial software that we have purchased. Step 1 was install the software using its JAVA Based installer ensuring that all files were installed into a particular directory in /usr/local. Step 2 was create a tar file of the

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

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 (Dsii - 2Dii A + A^2)/2; psvbar =

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 I can load all the data

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]; PSV = psv/Sqrt[2NN]; Print["------------- Results

I know that at the end of an R session I'm given the option to save the current *state* of the session. But I would like to save the entire sequence 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

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

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

Also sent to Codeweavers - [what is this list's insights?] I have a 32 GB, dual quad-core desktop machine and was considering 32-bit Windows XP w/SP2, but discovered it only supports up to 4 GB RAM, so that idea is shot. Next in line is 64-bit CentOS 5. The major need for Windows would be very active use of Adobe Acrobat 8, Photoshop CS3, and Illustrator CS3. There may also be the need

I''m not sure this is the appropriate community to get objective unbiased feedback on this issue, but I suppose it''s worth a gander... Here''s my question: Is it possible to write a massively scalable application intented for millions of users (i.e. Yahoo, Google, MySpace, etc.) using Ruby on Rails? I''m sure apps like these can be built, but can they scale to

I am working on a project that requires me to do very large factorial evaluations. On R the built in factorial function and the one I created both are not able to do factorials over 170. The first gives an error and mine return Inf. Is there a way to have R do these larger calculations (the calculator in accessories can do 10000 factorial and Maple can do even larger) -- View this message in
