Hello, Something incredible (at least for me) has happen. Yesterday night I downloaded biplot.R to edit this function and add new features I wished. Namely I wanted to plot points belonging to different groups using different colors and symbols. I identified which part of the original code I had to modify. Then, I rename biplot by biplotes and executing biplotes(x), being x a princomp class object, the function did what I wanted.
The problem is that today I type exactly the same (after sourcing my script file incluiding biplotes) but biplotes(x) execute the original biplot function. Also, if I invoke any of the new arguments I wrote in the code then multiple warnings messages are displayed. I don't understand what is the problem. Yesterday it works perfectly. Why R does not execute my code and call the original biplot function? Thanks in advance, Javier. -- View this message in context: http://www.nabble.com/Modifying-a-built-in-R-function-tp22278950p22278950.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ 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.
