...as by exclusion: "most types of objects are regarded as recursive, except for vector types, ?NULL? and symbols (as given by ?as.name?)." I think this that means recursive objects are: * lists * pairlists * calls * expressions Did I miss anything?

...? What cut off should I use? If it helps to be explicit, I'm interested in detecting when a vector is constant for the purpose of visual display. In other words, if I rescale x to [0, 1] do I have enough precision to get at least 100 unique values. Thanks!

...ll, Are there base functions that do the equivalent of this? fliptb <- function(x) x[nrow(x):1, ] fliplr <- function(x) x[, nrow(x):1] Obviously not hard to implement (although it needs some more checks), just wondering if it had already been implemented.

Hi all, Is there any chance that readRDS and saveRDS might one day become read.rds and write.rds? That would make them more consistent with the other reading and writing functions.

...de for readNEWS() it seems there are couple of places where it assumes it's working with the main R NEWS file: * s.post <- " SERIES NEWS" * s.pre <- "^[\t ]*CHANGES IN R VERSION " Is this a bug or is the documentation incorrect?

Hi all, If a package suggests another package in its description, you can check it at runtime with requires. How do you do check if a package is available without loading it, if you only want to access one function in the package namespace.

Hi all, Does anyone have an R implementation of the queplot (K.?M. Goldberg and B.?Iglewicz. Bivariate extensions of the boxplot. Technometrics, 34(3):pp. 307?320, 1992)? I'm struggling with the estimation of the asymmetry parameters. Hadley -- Assistant Professor / Dobelman Family Junior Chair Department of Statistics / Rice University http://had.co.nz/

...-forward, cross-platform way of determining if a user has all the tools needed to develop R packages (i.e. gcc etc)? It doesn't need to be 100%, but should give a rough idea. One idea I had was simply to see if system("R CMD install --help") worked. Hadley -- Assistant Professor / Dobelman Family Junior Chair Department of Statistics / Rice University http://had.co.nz/

Hi, Is there such a thing? If no: is it easily simulated? thanks, Joh

...9;m not looking for anything robust - I want some way of printing output to the screen that the user can't read immediately, but can decrypt a little later. The main thing I don't want to the user to see is a number, so (e.g.) ROT13 isn't appropriate.

Dear All, a quick xtable question. I do have quite a bunch of tables in my latex document which I produce with xtable. That works fine so far. But I wonder is it possible set some values such as "environement", "caption.placement", or "size" globally so that it applies for table unless otherwise specified? If anybody has quick fix, that would be helpful. Thanks and

Hi all, Since roxygen is a great help to document R packages, I am wondering if there exists an approach to go back from the raw Rd files to roxygen-documentation? E.g. turn "\author{Somebody}" into "@author Somebody". This sounds ridiculous, but I believe it helps in the long term for me to maintain R packages. Thanks! Regards, Yihui -- Yihui Xie <xieyihui at

Hi all, Does anyone have any advice or experience storing package settings between R runs? Can I rely on the user's home directory (e.g. tools::file_path_as_absolute("~")) to be available and writeable across platforms?

...uot;, group = Subject) But in base graphics, the best I can come up with is this: with(Oxboys, plot(age, height, type = "n")) lapply(split(Oxboys[c("age", "height")], Oxboys$Subject), lines) Am I missing something obvious?
