Hi, I'm trying to install RSPython v0.5-4 on a debian machine (woody, testing) but am having the following problem. $R CMD INSTALL -c --library=/usr/lib/R/library RSPython_0.5-4.tar.gz 2>err But then... $python >> import RS Error in .PythonInit() : Error in Python call: values Error in library("RSPython") : .First.lib failed for 'RSPython' Traceback (most recent

I am a long time user of R for financial time series analysis (xts, zoo, etc) and for my next project I am thinking of adding the Python language to the mix. The reason for adding Python is primarily its non-statistical capabilities. So my questions are what have people's experiences been with using interop between R and Python. I see there are two items, rPy and RSPython. It looks like rPy

Hello, My platform is SuSE 8.1. After downloading and unpacking R version 1.7 I tried building with shared libs enabled. (./configure --enabl-R-shlib). My goal is to use RSPython but I am now in my own private segmentation fault hell. The R build worked fine: make, make check, make install cool. The RSPython build worked fine. Thinking I'm good to go, I run python. But when I import RS

Hi, where is the latest version of the RSPython library? Is it compatible with the current stable release of R? Thanks, Darren

I am trying to install Rpy to test it out as an R interface for a project that I am working on. However, I get the following error. Any clues as to what might be going on? I have alo tried RSPython, but I gave up due to errors. RSPython segfaults when started from R and gives an error message I can;t remember from python. Thanks, Brett >>> import rpy Traceback (most recent call

Hello. I'm not a regular subscriber in this mailing list, but I think that this announce may interest somebody. Please, forgive me if this is the wrong place. Based on the code of RSPython, but modifying it a little, I wrote an interface for using R from Python. The main reason for writing it was to make it robust, in order to avoid segmentation faults. Also, it is (IMMO) a very

Hi, I'm planning to write some code in Python using R functions. I'm aware of the two R<->Python packages - Rpy and RSPython. Rpy seems easier to get up and running with, but does anybody have any comments regarding which would be a better system to work with in the long run?

How can I parse a YAML file in R 2.6.0 in Windows? I cannot get the RYaml package to compile in Windows, I can't find a MinGW compiled .dll for an existing YAML parser like syck (which would appear to be the best hope for creating my own R wrapper functions), and I don't know how to call a Ruby or Python function from R (so that I could parse the file in Ruby or Python and pass the parsed

Hi all, I need the power of R from within some of my Python programs... I use debian linux (woody) at home and windows XP at work (the latter is where I need to get things done!) This are my packages: R 1.8.0 Python 2.3 RSPython 0.5-3 This is what I've done: (1) Since the Windows Binary of RSPython is compiled against Python 2.2 I downloaded the tarball (2) Followed the instructions in

Hi Folks, After seeing some tips on the web, I managed to get RSPython-0.7-1 installed with R 2.9.0 (on Ubuntu 8.04). I had to get rid of the extra comma in the PythonPath function in Python.S: .PythonPath <- function(path=NULL, merge = TRUE) { dirSep <- ifelse(R.version$os == "Win32", ";", ":",) (remove last comma before bracket) and I had to manually

rPython appears to provide an interface from R to Python by embedding Python and I'd think that it can safely assume that R has been initialized, but might not be the point here. The issue is that a Python package embedding itself R (here rpy2) appears to have no way to know that earlier in the life of the process R was initialized. 2015-05-03 19:48 GMT-04:00 Duncan Murdoch

Dear list, Rpy is a python module that provides python interface to R. The following simple commands >>> from rpy import * >>> r.plot(0) is supposed to create a window that displays the result of plot(0). However, we observe that 1. Under *nix, rpy+R+python work as expected 2. Under windows, python + pythonWin32 (a python GUI provided by the pywin32 module), work as expected

Hi! Given a vector (or a factor within a df),i.e. v1 <- c(1,1,1,2,3,4,1,10,3) and a dictionary cbind(c(1,2,3),c(1001,1002,1003)) is there a function (on the same line than recode() in car) to get v2 as c(1001,1001,1001,1002,1003,4,1001,10,1003) ? I'm using myself a function based on match() since long ago (I think that thanks to advice by Prof. B. Ripley), but would like to know if there

Hi! Is there any way of having a greyed ("ghosted") text (i.e, 2006) in the background of a plot? I'm making a dynamic plot and would like to show the year of each time step as a big greyed text in the background. (the idea comes from Hans Rosling video: http://video.google.com/videoplay?docid=4237353244338529080&sourceid=searchfeed ) Thanks Agus -- Dr. Agustin Lobo Institut

Hi! Is not there an standard R function to retrieve the day of the year (since 1st Jan of the same year)? I know I can make my own using julian, but find it weird that having days(), months() etc doy() does not exist as an standard function. Also, is the following not a bit inconsistent? > a <- chron("20100506",format="ymd") > a [1] 100506 > years(a) [1] 2010

Hi! Is it possible to set a file to which both commands and output would get automatically saved? I've tried with sink(), but only get the output. I mean something like a combined history and sink, as you get with File/Save to File.. in the windows GUI. Tis is done with diary filename in Matlab, and you can state diary on and diary off to control what is being saved to the file. Thanks Agus

I'm doing: > alyL32007z <- zoo(alyL32007,alyL32007$time) > range(time(alyL32007z)) [1] "2007-01-01 00:00:00 UTC" "2007-12-31 23:30:00 UTC" But then, while the original variable is: > summary(alyL32007$NEE_st) Min. 1st Qu.

Dear List, I'd like to call pyhton function from within R. I tried installing the latest version of RSPython: wget http://www.omegahat.org/RSPython/RSPython_0.7-1.tar.gz R CMD INSTALL --clean RSPython_0.7-1.tar.gz I get a compile error (posted below).
