Hi r-devel,
The R_ParseVector has been changed in R-2.5.0, and there is a simple
description about the 4th argument at
http://stat.ethz.ch/R-manual/R-patched/NEWS, it says that:
"R_ParseVector() has a new 4th argument 'SEXP srcfile' allowing source
references to be attached to the returned expression list. "
I do not quite understand the purpose of adding the 4th argument. Would some
experts explain this function in details?
Thank you very much!
