I'm just curious. Why making "if" generic is even more dangerous? Best, Da On Sat, Mar 4, 2017 at 1:22 PM, G?bor Cs?rdi <csardi.gabor at gmail.com> wrote: > `!` is a generic, `if` is not.

Dear R developers, I am seeking advice on some $subject matter. My package will have an update soon, that is not backward compatible with the current version. It will likely break much of the existing code. Many (~50) packages depend on 'igraph' and they, too, will most probably break with the new version. My intended solution is, that I create a snapshot of the current package, under

Yeah, I agree, paste's recycling rules are sometimes painful. This could be "fixed" with a nice

Yes, indeed it seems that old OpenSSL versions cannot handle

Was this resolved upstream or is this something that R should/could fix? If the latter, could this also go into the "emergency release" R 4.0.2 that is scheduled for 2020-06-22?

In my case, I create a new type of matrices and override matrix operations in R for these matrices. My goal is to make the system as transparent as possible, which means my system should execute the existing R code without modification. The problem is that when data is in my own vectors or matrices, "if" or "while" can't access their values unless we explicitly convert them

Dear All, in some functions of my package, I use the Matrix S4 class, as defined in the Matrix package. I don't want to depend on Matrix, however, because my package is perfectly fine without Matrix, most of the functionality does not need Matrix. Matrix is so included in the 'Suggests' line. I load Matrix via require(), from the functions that really need it. This mostly works

Yeah, I get that they are async. What happens is that the background process is not doing anything when the process gets a SIGINT. I.e. the background process is just listening on its standard input. AFAICT for an interactive process such a SIGINT is just swallowed, with a newline outputted to the terminal. But apparently, for this background process, it is not swallowed, and it is triggered

Thanks. Can I override it for a specific class? I can do that for operators such as "!". For example, "!.fm" works for objects of the class "fm". It seems I can't do the same for "if".

Sorry for not reading carefully and thanks for confirming problem with Rscript too.

Dear All, [ I was wondering if this should have gone to the new mailing list. Maybe. ] As some of you maybe know from my earlier posts, I am building a simple search engine for R packages. Now the search engine has a proper web site, where you can also browse CRAN packages. http://www.r-pkg.org/ As I see the value is in 1. package search (search box on top right) 2. APIs, see

I am not sure if this is a bug or not.

OK, I managed to create an example without callr, but it is still somewhat cumbersome. Anyway, here it is. Terminal 1: mkfifo fif R --no-readline --slave --no-save --no-restore < fif Terminal 2: cat > fif Sys.getpid() This will make Terminal 1 print the pid of the R process, so we can send a SIGINT: Terminal 3: kill -INT pid The R process is of course still running happily. Terminal 2

Dear all, "Writing R Extensions" explicitly says that A method must have all the arguments of the generic, including ... if the generic does. A method must have arguments in exactly the same order as the generic. If the generic specifies defaults, all methods should use the same defaults. This is clear. R CMD check even checks for this. But then how is it possible that

Dear All, I would like to do run R without having write permissions to any directory on the system. It seems that I need to modify the R source code for this, to make R start without creating a temporary directory. So far, so good. But should I expect any more complications? Does R really need the temporary directory that much? Thanks, Gabor -- Gabor Csardi <Gabor.Csardi at unil.ch>

The max argument of print.default() does not override options(max.print), see below. R 3.5.1 and R-devel both seem good.
