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). Did anyone else run against this ? Is there a solution ? checking for python... /usr/bin/python Python version 2.6 Using threads checking

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

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

I can compile RSPython without difficulty, been when I try to load it, I get the error messages below. Also below are some cryptic warnings I get on R boot (in case these are pertinent) and my sessionInfo(). Any help is appreciated. Thanks, Mark Warning messages: 1: In .updateMethodsInTable(fdef, where, attach) : Couldn't find methods table for "conditional", package

Hi all, I try to utilize RSPython to invoke Python from R. For me it works pretty fine for basic applications, but I have 3 problems that may be related. (1) I can't load other packages but "standard" ones also when I adjust the PythonPath: > importPythonModule('sys', all=T) NULL > importPythonModule('numpy', all=T) Error in

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

I just followed the instructions on CRAN<http://cran.r-project.org/bin/linux/ubuntu/README> to install R on an Ubuntu instance. sudo apt-get install r-base Why does it install an old version of R? Can I install version 15.1? I changed my sources.list to be a current cran mirror. I believe that I have entered the URL correctly because at first I had it wrong (there was a trailing

To get RSPython installed on my debian test box, I had to make a couple of changes not listed in ftp://www.omegahat.org/pub/Omega/RSPython/FAQ.html 1) I had to change $R_HOME/src/modules/X11 : $(R_X11_la): $(R_X11_la_OBJECTS) $(R_X11_la_DEPENDENCIES) $(SHLIB_LINK) -o $@ $(R_X11_la_LDFLAGS) $(R_X11_la_OBJECTS) $(R_X11_la_LIBADD) $(LIBS) to $(R_X11_la): $(R_X11_la_OBJECTS)

My apologies, I know that this is not a new problem, but I'm not sure how to find the answer I want to recursively loop over an object and trim trailing white space. When I use this function on a list of data.frame I get output like this: [1] "c(\" many spaces \", \" many spaces \")" "c(\" many spaces \", \" many spaces

I thought the "apply" functions are faster than for loops, but my most recent test shows that apply actually takes a significantly longer than a for loop. Am I missing something? It doesn't matter much if I do column wise calculations rather than row wise ## Example of how apply is SLOWER than for loop: #rm(list=ls()) ## DEFINE VARIABLES mu=0.05 ; sigma=0.20 ; dt=.25 ; T=50 ;

Why doesn't this work? x = zoo(1:5, as.Date('2001-01-01')+1:5) x[as.Date('2001-01-05')] x[as.Date('2001-01-05')] = 0 x I think this is especially bad because it doesn't cause an error. It lets you do something to x, but then you can't see x again to see what it did. [[alternative HTML version deleted]]

** Disclaimer: I'm looking for general suggestions ** I'm sorry, but can't send out the file I'm using, so there is no reproducible example. I'm using read.table and it's taking over 30 seconds to read a tiny file. The strange thing is that it takes roughly the same amount of time if the file is 100 times larger. After re-reviewing the data Import / Export manual I think

Does anyone know how to pass a list of parameters into a function? for example: somefun=function(x1,x2,x3,x4,x5,x6,x7,x8,x9){ ans=x1+x2+x3+x4+x5+x6+x7+x8+x9 return(ans) } somefun(1,2,3,4,5,6,7,8,9) # I would like this to work: temp=c(x3=3,x4=4,x5=5,x6=6,x7=7,x8=8,x9=9) somefun(x1=1,x2=2,temp) # OR I would like this to work: temp=list(x3=3,x4=4,x5=5,x6=6,x7=7,x8=8,x9=9)

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? Thanks, ------------------------------------------------------------------- Rajarshi Guha <rxg218 at

I've been wondering what L means in the R computing context, and was wondering if someone could point me to a reference where I could read about it, or tell me what it's called so that I can search for it myself. (L by itself is a little too general for a search term). I encounter it in strange places, most recently in the "save" documentation. save(..., list = character(0L),

On the Mac it's pretty easy to get to a USB drive by name. For example the following command works if you have a USB drive named "MYUSB" setwd('/Volumes/MYUSB') Is there a way to do the same thing in Windows (without knowing the drive letter)? Thanks! [[alternative HTML version deleted]]

I don't understand how this function can subset by i when i is missing.... ## My function: myfun = function(vec, i){ ret = vec[i] ret } ## My data: i = 10 vec = 1:100 ## Expected input and behavior: myfun(vec, i) ## Missing an argument, but error is not caught! ## How is subsetting even possible here??? myfun(vec) Is there a way to check for missing function arguments, *and*

A question for a (experienced) user of the RPython package on linux. I'm trying to call R from python on a linux (Suse 7.3) box. After installing R CMD INSTALL -c RSPython_0.5-2.tar.gz I start python and do: >>> import sys >>> sys.path.append('/usr/local/lib/R/library/RSPython') >>> sys.path.append('/usr/local/lib/R/library/RSPython/Python')

Dear R users, I have now managed to fit the curve using the thin plate spline as follows: library(mgcv) b <- gam(y~s(x1,x2,k=100),data =dat) vis.gam(b) What I want now is to get the fitted data for y and copy it so that I use it for further analysis. Many thanks in advance mintewab

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
