Dear all,
my aim is to integrate R in an interactive visualisation software
called Bulk Analyzer developed by VrVis (http://www.vrvis.at).
the code:
SEXP e, tmp;
ParseStatus status;
PROTECT(tmp = mkString("x <- c(1.234,-3.45)"));
PrintValue(tmp);
PROTECT(e = R_ParseVector(tmp, -1, &status, R_NilValue));
PrintValue(e);
UNPROTECT(2);
produces the following output:
[1] "x <- c(1.234,-3.45)"
expression(x <- c(1, -3))
I'm using MS Visual C++. The code works fine in a small test project
with the same R startup settings (attached) as in the Bulk Analyzer
project.
Is there any setting or condition for this parser behaviour?
Kind regards,
Roland N. Boubela
