...ot;)] The variable attribute, in the terms object, keeps them as quotes, so modeling code that uses that attribute seems fine, but code that uses the term.labels fails. In particular, it seems (of those tested) that glm, lda, randomForest seem to work fine, while nnet, rpart can't handle nonsyntactic names in formulae as such In particlar, rpart contains this code: lapply(m[attr(Terms, "term.labels")], tfun) which fails for the reasons given. One way to get around this, might be to modify the do_termsform code, right now we have: PROTECT(varnames = allocVector(STRSX...

(PR#7205) o The GNOME interface was in some circumstances failing if run from a menu -- it needed to always specify that R be interactive. o depMtrxToStrings (part of pkgDepends) applied nrow() to a non-matrix and aborted on the result. o Fix some issues with nonsyntactical names in modelling code (PR#7202), relating to backquoting. There are likely more. o Support for S4 classes that extend basic classes has been fixed in several ways. as() methods and x at .Data should work better. o hist() and pretty() accept (and ignore) infinite values.
