similar to: Ops.data.frame fails with second arg a list (PR#1889)

Inside of the anyNA() function, it will use the legacy any(is.na()) code if x is an OBJECT(). If x is a vector of POSIXct, it will be an OBJECT(), but it is also TYPEOF(x) == REALSXP. Therefore, it will skip the faster ITERATE_BY_REGION, which is typically 5x faster in my testing. Is the OBJECT() condition really necessary, or could it be moved after the switch() for the individual TYPEOF(x)

Hi, I would be nice if names() returned the equivalent of ls() for environments. --- a/src/main/attrib.c +++ b/src/main/attrib.c @@ -687,6 +687,8 @@ SEXP attribute_hidden do_names(SEXP call s = CAR(args); if (isVector(s) || isList(s) || isLanguage(s)) return getAttrib(s, R_NamesSymbol); + if (isEnvironment(s)) + return R_lsInternal(s, 0); return R_NilValue; }

I am currently puzzled by a passage in the R Extensions manual, section 5.10: SEXP lapply(SEXP list, SEXP expr, SEXP rho) { R_len_t i, n = length(list); SEXP ans; if(!isNewList(list)) error("`list' must be a list"); if(!isEnvironment(rho)) error("`rho' should be an environment"); PROTECT(ans = allocVector(VECSXP, n));

I see some value in Duncan?s proposal to implement this as an extra package instead of a change to base R, if only to see if the idea has legs. I?m minded to do so myself using your suggestion, but is there a particular reason why you recommend using the remotes package instead of devtools? The latter seems to have the same functions I would need, and I believe it is more widely installed that

Thanks for the help on the translucent dots. What would be the best method for creating a map of the facility? I looked into map* in the libraries and didn't find anything on creating the maps, just using them. Thanks again...

Would you care to share how your package installs its own dependencies? I assume this is done during the call to `main()`? (Last time I checked, R CMD INSTALL would not install a package's dependencies...)

In S, NULL and list() are not the same. In R they are (I think). --------------------------------------------------- At least, is.list(NULL) #-> 'F' in S; 'TRUE' in R Yes: I had an instance where this broke correct S code: match(c("xlab","ylab"), names(list(...))) when '...' is empty, gives an error in R, but gives c(NA,NA) in S.

I can set up an entry widget (thanks to an old post by Barry Rowlingson) that gets a password and exits when the user clicks on the "OK" button. Anyone have any clever ideas for returning/ destroying the window when the user types a carriage return/ENTER in the text window? I've messed around a little with validate, validatecommand, but don't see any obvious way to do it ...

Yes, the performance overhead of fixing this at R level would be too large and it would complicate the code significantly. The result of binary operations involving NA and NaN is hardware dependent (the propagation of NaN payload) - on some hardware, it actually works the way we would like - NA is returned - but on some hardware you get NaN or sometimes NA and sometimes NaN. Also there are C

Dear Barry, In general, I believe users are already accustomed with the classical arrows "->" and "<-" which are used as such in quoted expressions. But I agree that "-.>" is a very neat trick, thanks a lot. A small dot, what a difference.
