[R] Code in lattice::dotplot function.
Hi, I'm trying to understand the code of lattice functions so that I can write some S4 methods using lattice. The following code is a snipet of dotplot that is reused in several other functions. I don't understand why this is needed can someone help ? Thanks EJ [...] right.name - deparse(substitute(formula)) try(formula - eval(formula), silent = TRUE) foo - substitute(formula) if (!(is.call(foo) foo[[1]] == ~)) { formula - as.formula(paste(~, right.name)) # deparse(foo))) environment(formula) - parent.frame() } [...] __ 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
