I don't. The order of evaluation is usually not readily observable. You either have to use <<- to modify an external variable or you have to produce printed or graphical output where the order matters. There's probably some examples, but there are some examples of people using solve(t(X) %*% W %*% X) %*% W %*% Y to compute regression coefficients, too. -thomas ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
