Dear list, When I read some source code, I find lot of place used symbol <<- , e.g.
lastTime <<- newTime; What is the meaning here? Also, I find some method with the name start with dot, e.g. .RowStandardizeCentered = function(x) { div = sqrt( rowSums(x^2) ); div[ div == 0 ] = 1; return( x/div ); } What is the special meaning for the method name start with a dot? Thank you very much in advance. ______________________________________________ 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.
