I found this part in the documentation of 'factor'. 'factor(x, exclude=NULL)' applied to a factor is a no-operation unless there are unused levels: in that case, a factor with the reduced level set is returned. If 'exclude' is used it should also be a factor with the same level set as 'x' or a set of codes for the levels to be excluded.

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

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

SVN revision replaces "slave" with "no-echo" in R devel. In each of the following, "no-echo" is rather strange to me. - src/gnuwin32/README.Rterm 3) As a no-echo process for ESS mode in NTEmacs with flag --ess. - src/library/grDevices/src/qdCocoa.m /* the no-echo thread work until this is NO */

...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.

Yes, they work now.

I have suggestions for function 'diff.default' in R. Suggestion 1: If the input is matrix, always return matrix, even if empty.

\b is word boundary. But, unexpectedly, strsplit("dia ma", "\\b") splits character by character. > strsplit("dia ma", "\\b") [[1]] [1] "d" "i" "a" " " "m" "a" > strsplit("dia ma", "\\b", perl=TRUE) [[1]] [1] "d" "i" "a" " "

In example for function 'stop' in R, there is options(error = expression(NULL)) with comment # don't stop on stop(.) << Use with CARE! >> I was interested, wanted to know how "don't stop on stop(.)" was. So, I tried it. Typing example(stop) at the R prompt and pressing ENTER give this. > example(stop) stop> options(error = expression(NULL))

useNA <- if (missing(useNA) && !missing(exclude) && !(NA %in% exclude)) "ifany" An example where it change 'table' result for non-factor input, from https://stat.ethz.ch/pipermail/r-help/2005-April/069053.html : x <- c(1,2,3,3,NA) table(as.integer(x), exclude=NaN) I bring the example up, in case that the change in result is not intended.
