Controlling stdin and stdout in an embedded R instance
...to the
ptr_R_ReadConsole and ptr_R_WriteConsole function pointers defined in
Rinterface.h but do not know if this is a valid approach. I am working
in Ubuntu 10.04 and thus the Windows example at the following address is
not applicable.

with an embedded R console using native R commands and consuming the
output one command at a time in a "Unix-alike" environment?
Thank you,

Windows environmental variables
...ssion running
on Windows, due to the way that R Sys.getenv works, which I would
consider a bug. Even if you do not agree, then you may still want to
document it for future users who might be bitten.

I actually found that I needed R_HOME/binR_ARCH instead: you may want
to update this).
There are 2 ways to get & set environmental variables in Windows (I
just discuss the UTF16 "widechar" methods):

getDLLVersion
Hi,
I'm just learning to write R extensions in C and to embed R in C.

directly (
http://cran.r-project.org/doc/manuals/R-exts.html#Calling-R_002edll-directly
).
When I compile I consistently get the error that getDLLVersion() as well as
get_R_HOME() and getRUser() are undefined references.
These are defined in Rembedded.h ln60 as:
extern char *getDLLVersion(void), *getRUser(void), *get_R_HOME(void);
I included Rembedded.h from the example....
