Issue when calling deparse(substitute(x)) from C with "anonymous" R vectors ?
...te this, I am using rpy2 (as the problem was found when using it http://sourceforge.net/mailarchive/forum.php?thread_name=4B043CA1.9050500%40salilab.org&forum_name=rpy-list ), but it will likely be present in other bridges to R as well. #using R-2.10 and rpy2-2.1.dev >>> import rpy2.robjects as robjects >>> f = robjects.r('''function(x) return(deparse(substitute(x)))''') >>> tuple(f(robjects.FloatVector(range(17)))) ('c(0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16)',) # length 1 >>> tuple(f(robjects.FloatVector...

Setting up a windows system for rcpp
I am running into a wall getting my system to work with rcpp and inline. Following Dirk's advice on stackoverflow, I hope someone is able to help me.

RSPerl...
Duncan - (but sent to R-devel, for any other thoughts?) How do you envision RSPerl being used? Without having seen the details, I can think of playing with strings; is there a preferred incantation for stringification of R objects (serialization)? (actually, the main problem I'm having is that I know how I want to code something like: Robject <-

In Python, it is literally this easy: import rpy2.robjects as robjects robjects.r(""" source("C:/ YOUR R FILE GOES HERE ") """) Type the name of your R source code into this script and save it as a Python script (add the suffix .py), and then you can run by double-clicking.

C-API: check whether R has been initialized ?

Possible bug: How does libR.so find RHOME?
...OME path to my R-2.9 library build explicitly to RPy2's setup.py by means of an environment variable that is checked by the script. This resulted in an RPy2 installation properly linked to my R-2.9. However, on starting RPy2 in Python, I got this strange error: >>> from rpy2 import robjects Error in grep("(_US|_CA)", lcpaper) : 8 arguments passed to .Internal(grep) which requires 9 [...] RPy2 started up nevertheless, but failed to load the base packages, so that all standard functions were missing.

Rcpp segmentation faults on the simplest code
Hi all, I'm new to R and Rcpp, and I'm trying to learn Rcpp with the simplest code possible. My goal is to be able to call R functions from C++. The code I'm trying to run is: #include #include #include #include int main(int argc, char* argv[]) { Rcpp::NumericVector v(1); return 0; } It compiles and links fine. However, as soon as I run it, it segfaults. The following is
