similar to: Extract.data.frame.Rd about $.data.frame

In R devel, data.frame method of '$' has been removed, but this part of "Details" section of Extract.data.frame.Rd still implies existence of the method. The \code{data.frame} method for \code{$}, treats \code{x} as a list, except that (as of R-3.1.0) partial matching of \code{name} to the names of \code{x} will generate a warning; this may become an error in future

http://stackoverflow.com/questions/6065724/assigning-value-to-a-variable-that-has-a-dot-in-the-name made me realize this. The context is 'a' is assigned to ret$log.id, but then ret$log returns "a" and ret$l also returns "a". There is a comment from Charles on the question: "Also see options(warnPartialMatchDollar=T) if you want to track these." But, in

Removal of ans[nas] <- NA from the code of function 'ifelse' in R is not committed (yet).

By "an argument named 'use.names' is included for concatenation", I meant something like this, that someone might try. > c(as.Date("2016-01-01"), use.names=FALSE) use.names "2016-01-01" "1970-01-01" See, 'use.names' is in the output. That's precisely because 'c.Date' doesn't have 'use.names', so

I am trying once again. By just changing f <- match(xlevs[f], nlevs) to f <- match(xlevs, nlevs)[f] , function 'factor' in R devel could be made more consistent and back-compatible.

Another possible shortcut definition: assert <- function(exprs) do.call("stopifnot", list(exprs = substitute(exprs), local = parent.frame())) After thinking again, I propose to use ??? ? ? stop(simpleError(msg, call = if(p <- sys.parent()) sys.call(p))) - It seems that the call is the call of the frame where stopifnot(...) is evaluated. Because that is the correct context, I

While you are fiddling with stopifnot(), please consider changing the form of the error thrown so that it includes the caller's call. The change would be from something like stop( <<the message>> ) to stop(simpleError( <<the message>>, sys.call(-1))) For the following code f <- function(x, y) { stopifnot(x > y) x - y } g <- function(x,

>From an example in http://www.uni-muenster.de/ZIV.BennoSueselbeck/s-html/helpfiles/nargs.html , number of arguments in '...' can be obtained by (function(...)nargs())(...) . I now realize that sys.call() doesn't expand '...' when the function is called with '...'. It just returns the call as is. If 'stopifnot' uses sys.call() instead of match.call() , the

While you are editing that, you might change its name from 'stderr' to standardError (or standard_error, etc.) so as not to conflict with base::stderr().

In R devel r72789, the added part in 'factor' documentation (factor.Rd) is the following. Undocumentedly for a long time, \code{factor(x)} loses all \code{\link{attributes}(x)} but \code{"names"}, and resets \code{"levels"} and \code{"class"}. In the code of function 'factor', names(x) is copied to the result. As I mentioned before, names(x) is _not_

On 'aggregate data.frame', the URL should be https://stat.ethz.ch/pipermail/r-help/2016-May/438631.html . vector(typeof(ans)) (or vector(storage.mode(ans))) has length zero and can be used to initialize array. Instead of if(missing(default)) , if(identical(default, NA)) could be used. The documentation could then say, for example: "If default = NA (the default), NA of appropriate

Ah, with R 3.5.0 or R 3.4.2, but not with R 3.3.1, 'eval' inside 'for' makes compiled version behave like non-compiled version. options(error = expression(NULL)) library(compiler) enableJIT(0) f <- function(x) for (i in 1) {x; eval(expression(i))} f(is.numeric(y)) # Error: object 'y' not found fc <- cmpfun(f) fc(is.numeric(y)) # Error: object 'y' not found
