How to get an object name from C?
(earlier I sent it as html by mistake).
Hi,
How can I get from C an object name used as a function argument? I
have sample code in C that gives me access to the name of the function
being called:
SEXP xname(SEXP x)
{
const char *fun_name = CHAR(PRINTNAME(CAR(x)));
x = CDR(x);
const char *arg_name = isNull(TAG(x)) ? "" : CHAR(PRINTNAME(TAG(x)));

R as chart engine in web-service
Hi R-users
I think about some web service with stock charts and I plan use python as
web framework with R as mathematical and chart engine. I use rpy to connect
R with python. It works good.
Is it good idea to use R as chart engine? Maybe it's better (faster) to use
c/c++ plugin?
