...g the same exercise. Start by defining foo() which evaluates an expression locally in a given environment and catches the output via capture.output(): foo <- function(..., envir=parent.frame()) { capture.output({ eval(substitute({x <- 1}), envir=envir) }) } # foo() Then call: > suppressWarnings(rm(x)); foo(envir=globalenv()); print(x); character(0) [1] 1 This works as expected. However, if argument 'envir' is not specified explicitly, you get: > suppressWarnings(rm(x)); foo(); str(x); character(0) Error in str(x) : object 'x' not found which shows that the internal...

G'day all, I have daily scripts running to install the patched version of the current R version and the development version of R on my linux box (Ubuntu 18.04.2 LTS). The last development version that was successfully compiled and installed was "R Under development (unstable) (2019-02-25 r76159)" on 26 February. Since then the script always fails as a regression test seems to

The suppressMessages and suppressWarnings functions currently suppress all the message or warnings that are generated by the input expression. The ability to suppress only specific messages or warnings is sometimes useful, particularly for cases like file import where there are lots of things that can go wrong. Suppressing only messages...

How can I suppress this warning? > options(warn = -10) > list(1,2,3,) Warning: a final empty element has been omitted the part of the args list of 'list' being evaluated was: (1, 2, 3, ) [[1]] [1] 1 [[2]] [1] 2 [[3]] [1] 3 > suppressWarnings(list(1,)) Warning: a final empty element has been omitted the part of the args list of 'list' being evaluated was: (1, ) [[1]] [1] 1 And can anyone add some insight as to why this warning was added?

HOWEVER, I want, in this odd case, to say "keep going" to my function and have it proceeed to # Do something C. How do I accomplish this? I thought suppressWarnings() would do it but it doesn't appear to. Assume that debugging "Do something B" is out of the question. Why am I doing this? Because in my odd case, "Do something B" actually does what I needed it to, but returned an error that is irrelevant to my special case (it creates...

...33d730/src/library/base/R/time.R#L31 on.exit(cat("Timing stopped at:", ppt(proc.time() - time), "\n")) This means that as far as I can tell the general way to make sure there is no output from a timed statement is ... tt1 <- capture.output(tt0 <- suppressMessages(suppressWarnings( try(<stuff to try>, silent=TRUE)))) (I know I could/should be using tryCatch() instead of try(), but I don't think it really matters here ... ?)

Dear R-users I need to read some text files produced by some other software. I used readLines (with n = -1 ) command and then tried to find some numbers I liked to extract or some line numbers I like to know. The problem is that there is no empty line at the end of the text files. R gave me this warning below; In addition: Warning message: incomplete final line found by readLines on

...coefficients ..." followed with a lot of numbers depending on the input. This is very annoying because I have to run that function several times and I don't want to show this information. What I want is to disable that display but I don't know how to do it. I've tried it with suppressWarnings ( function (...) ) and suppressMessages ( function (...) ) but It doesn't work, the function() continues printing that information. I tried invisible () too. Furthermore, this function doesn't have a "verbose" parameter. Thus, I can't disable it using a verbose parameter....

Suppose I have a vector of strings. I'd like to convert this to a vector of numbers if possible. How can I tell if it is possible? as.numeric() will issue a warning if it fails. Do I need to trap this warning? If so, how? In other words, my end goal is a function that takes a vector of strings and returns either a numeric vector or the original vector. Assuming this doesn't already

.... Otherwise keep the output of the function. I'm not sure how to create the above construct. The code I have below doesn't work: __BEGIN__ myfunction <- function(the_x) { # do something a = list(output1=val1, output2 = val2) a } out <- try(suppressWarnings(myfunction(x)),silent=T) if (class(out) == "try-error") { #this clause doesn't seem to "redo" out <- myfunction(X) } else { ll <- out$output1 } __END__ - Gundala Viswanath Jakarta - Indonesia
