Is the following expected behavior?> mkext <- inline::cfunction(language="C", body='return R_MakeExternalPtr(NULL, install("tag"), R_NilValue);')
> x <- mkext() > y <- x > attr(y, "foo") <- "bar" > attributes(x) $foo [1] "bar"
I would expect that modifying y's attributes should not affect x. [Tested on R version 3.3.3 x86_64-apple-darwin16.4.0 (64-bit)] Thanks, Patrick ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
