eval(SEXP fn,SEXP rho) in C++ code
Hi r-devel, I am working on a R extension. I am writing the function in C++, and in my function it is required a R function object from the user. This R function object will be evaluated thousand of times in my C++ code. I generated the shared library and I loaded it on R. I did several experiments in order to compare the speed of my compiled code vs the speed of the equivalent interpreted code.

rsync and SSL: gettig the patch working
Hi all, I have applied the patch at http://metastatic.org/source/rsync-ssl.patch to the rsync v2.6.2 tree, and have it installed between two hosts. Unfortunately the patch contains no docs, so I have no idea whether I've configured it correctly. Any attempt at making an rsync transfer bombs out with the error: [fma@chandler fma]$ rsync -a --ssl-ca-certs=/usr/share/ssl/certs/caCert.pem

Internal functions
I've complex problem and this's idealization of it: v=1:10 fx<-function(x){ v[x]=v[x]*2} fy<-function(y){ fx(y)} for(i in 1:10){ fy(i)} How to modife expresion (and only that): {v[x]=v[x]^2} to achive the redefinetion of the values of vector v, the result should be: v=(1:10)*2. I think, that could be done with using of internal functions, but I'm not the programmer.
