So in English what you are saying is that there's a file called Makeconf in the etc directory under the R_HOME that contains the information. That certainly seems to be true for Linux.

I did have a search, but searching for "configure" just brought up loads of results for how to configure R. I'm sure it is in the manual, once you know where to look for it and if you know all the manuals inside out. Looking at the help for R CMD config, it's not actually clear that these relate to the options specified on configure, and it doesn't tell you things like

Yeah, that's often a possible workaround, but since this connection was opened by readLines() internally, I don't necessarily know which one it is. E.g. I might open multiple

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?

Consider this code. This is R 3.4.2, but based on a quick look at the NEWS, this has not been fixed. tryCatch( readLines(tempfile(), warn = FALSE)[1], error = function(e) NA, warning = function(w) NA ) rm(list=ls(all.names = TRUE)) gc() showConnections(all = TRUE) If you run it, you'll get a connection you cannot close(), i.e. the last showConnections() call prints: ?

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

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

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

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".

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

Hi to all, does anybody knows whether there is a package to plot those http://www.equine-science.de/temp/graph.jpg graphs. the thickness of the points and/or the lines should be represent the numbers of behaviours With kind regards Knut

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, "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
