No (how could it be? If anything, this has to do with _de_parsing). It's a bug (two, actually) in lattice, which has a maintainer.... Inside latticeParseFormula parseCond <- function(model) { model <- eval(parse(text = paste("~", deparse(model))))[[2]] model.vars <- list() .... and later on in the same function names(ans$condition) <- sapply(modelRHS.vars, deparse) both of which whill get you in trouble if deparse needs multiple lines. Notice that paste("~", deparse(model)) will prepend a "~" to _every_ line, where only the first was intended, so you could have gotten a parse error there and then. The first bug is the sort of construct that I have been warning people about repeatedly; computing on the language by going through the textual representation as in parse(...deparse(...)) is almost always wrong. In this particular case, I think the code is equivalent to model <- substitute(~ m, list(m = model)) (minus the bug, of course). Bug #2 is probably just that you need to take only the first line of deparse(), since you wouldn't want or need the fully deparsed object for a name. -- O__ ---- Peter Dalgaard Blegdamsvej 3 c/ /'_ --- Dept. of Biostatistics 2200 Cph.
