@yuyaxuan <309772...@qq.com> That code looks dangerous. I guessing it was written by an inexperienced R programmer and that 'loc' is a synonym for `which`. You should not be testing or equality of floating point numbers .... read the FAQ. I searched using findFn in the sos package, and could not find such a function, so my guess is that it was defined in the preceding code that you have not shown. -- David Winsemius, MD Alameda, CA, USA ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
