I hope that the source reference argument in the `function` calls is the last way a source reference could sneak by in an expression obtained using substitute(). > It's implemented in C for efficiency as we found it to be a > bottleneck in some applications (IIRC caching).

A removeSource() that handles all the corner cases would be a nice improvement. -- Best regards, Ivan ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
