It works by cooperating with message(). message() itself works by trying to raise a "message" condition and providing a "muffleMessage" restart that does nothing. If the condition wasn't handled (the "muffleMessage" restart wasn't called by the handler), the text of the message is printed. In turn, suppressMessages() sets up a handler for conditions of class "message" that invokes the "muffleM...

Hi all, I would like to create a function that detects if suppressMessages has been invoked upon running that same function. I was looking through {https://cran.r-project.org/doc/manuals/r-release/R-ints.html}, but I haven't found an answer. I do not understand **how** suppressMessages works. I have not received an answer on SO

...vided get muffled. Something like: suppressMessages <- function (expr, ids = NULL) { withCallingHandlers( expr, message = function(c) { if(is.null(ids) || (inherits(c, "simpleMessage") && c$id %in% as.character(ids))) { invokeRestart("muffleMessage") } } ) } The hard part is providing IDs for all the existing messages in R and its packages. It's certainly do-able, but I imagine would take quite a lot of time. Is there any enthusiasm for implementing this feature, or something like it? -- Regards, Richie Learning R...

...method is less likely to cause conflicts. Is it correct that you are proposing something that allows us to do: registerDefaultConditionHandlers( packageStartupMessage = function(c) { ## Do something with condition 'c' ... ## Suppress futher processing invokeRestart("muffleMessage") } ) at the core, which avoids having us to wrap up calls in withCallingHandlers() at top-level calls, e.g. > withCallingHandlers({ library("foobar"), }, packageStartupMessage = function(c) { ## Do something with condition 'c' ... ## Suppress futher processing...

Hi Luke, Thank you for your response. On 6/21/19 10:56 AM, Tierney, Luke wrote: Thanks for the suggestion. However I don't think it is the right way to go. I also don't care for what install.packages() does. Signaling a warning and then an error means someone has to catch both the error and the warning, or suppress the warning, in order to handle the error programmatically. I do care

Hi All: I am using httr to download files form a service, in this case a .csv file. When I use httr::content on the result, I get a message. Since this will be in a package. I want to suppress the message, but haven't figured out how to do so. The following should reproduce the result: myURL <-

Simon - which compiler)s) did you use: xlc and xlfortran, or gcc/gfortran? I have made some changes to configure(.ac) so maybe my problems are self-inflicted. But would be good to know what environment you are using. Thanks for looking - and

Dear R users, I have installed the latest version of R from source on Centos (using configure and make install). This seemed to work fine, with no Errors reported and R at the command line starts R. However, if I try and installed the package rgl using; install.packages("rgl") I get the following error; installing to /usr/local/lib64/R/library/rgl/libs ** R ** demo ** inst ** preparing
