Hello everyone. I have written a small function that returns a 3*n array where n is typicall between 5-55. I issued in R shweights<-shadowing_weights(x,xr) and I got the result in less that one sec. then I tried to see what is inside the shweights array and thus I issued the edit(shweights) which 10 mins right now is busy and got no reply yet back. As I am using rkward I tried from gui the

Please take a look at the values below ................. [31,] 30.000000000000000 30.000000000000000 [32,] 31.000000000000000 31.000000000000000 [33,] 32.000000000000000 32.000000000000000 [34,] 33.000000000000000 33.000000000000000 [35,] 34.000000000000000 34.000000000000000 [36,] 35.000000000000000 35.000000000000000 [37,] 35.999999999999872 35.999999999999872 These are entries in an array.

Hello everoyne, If you have ever used matlab you should know the variable editor. You click over the value of a variable in the workspace and it opens like a excel sheet. Do you know if there is something like that in R . This will make easier for me to understand what values are stored in a matrix. Also I am using rkward. Do you know if there is anyway to see the already defined variables?  I

Dear expeRts, I am struggling with warning/error handling. I would like to call a function which can produce either a) normal output b) a warning c) an error Since the function is called several (thousand) times in a loop, I would like to proceed "quietly" and collect the warnings and errors [to deal with them at a later point]. I have seen constructs with tryCatch (which can

Hello, I apologized if this had already been addressed, and I also submitted this problem on SO: http://stackoverflow.com/questions/20268021/how-to-catch-warnings-sent-during-s4-method-selection Example code: setGeneric('my_method', function(x) standardGeneric('my_method') ) setMethod('my_method', 'ANY', function(x) invisible())

Dear all, For an open-source project that I'm working on (1), which uses R for all its heavy lifting but includes a wrapper shell script, I was hoping to find a way to capture all warnings (and, in fact, errors too), and handle them in my own way. I realise I can do this for a single expression using something like: > f <- function(w) print(w$message) >

Well, following a discussion with Duncan Murdoch, where he suggests me to rewrite my requests, here it is. Just a couple of problems I found difficult to solve, as a writer of R GUIs, and for which I would be very happy to get a R function (plus rationates): - To know if an evaluation returns invisibly or not. This is discussed in a previous thread. We now have withVisible(). - To know if

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 that match a regular expression has rightly been rejected

With tryCatch() it is possible to catch interrupts with tryCatch(). Then you can use a 'finally' statement to clean up, release resources etc. However, how can I "protect" against additional interrupts? This is a concern when the hold down Ctrl+C and generates a sequence of interrupts. Example: tryCatch({ cat("Press Ctrl+C...\n"); Sys.sleep(5); }, interrupt =

My points: - The 'withCallingHandlers' construct that is used in current 'stopifnot' code has no effect. Without it, the warning message is the same. The overridden warning is not raised. The original warning stays. - Overriding call in error and warning to 'cl.i' doesn't always give better outcome. The original call may be "narrower" than 'cl.i'. I

Hi, folks! I'm trying to pull in data using read.csv("my URL goes here"), and it really works fantastically. Amazing to pull in live data right off the internet, into RAM, and get busy... however... occasionally there is a server problem, or the data are not up yet, and instead of pushing through a nice CSV file, the server sends a 404 "Not Found" page... Since the

When batch processing analysis, I use tryCatch() for failure handling and to prevent unwanted interrupts. I write detailed progress to log file and conditions (warnings and errors) are written to the same log file immediately by using withCallingHandlers(..., condition=function(c) cat(c, file=logFile)). However, I would also like to write the call stack to the log file to further simplify

Dear list! I have a script that processes a large number of data files. When one file fails to process correctly, I want the script to write a message and to continue with the next file. I achieved this with tryCatch: for (f in files) tryCatch({heavy.lifting(f)}, error=function(e) log.error.to.file(e)) I also want to log warning messages and tried something like this: for (f in

Dear list members, I have come about a peculiar behavior in R (4.0.2) which I would describe as a bug. On macOS, where `strptime()` raises a warning for invalid timezone identifiers, the following code will continue to raise the original warning with every subsequent call to `strptime()`: ``` # attach a handler for warnings for this call only: tryCatch(strptime('2020-10-31 18:30', format

Hi I need some help! I have controller that I need to pass a full url (with its own parametrs) as a parameter, e.g. I want to call my controller with: /mycontroller/catchurl?url=http://somedomain.com/afile.jsp?param1=xx&param2=yy and in action "catchurl" in mycontroller.rb I would like to have params[:url] to be "http://somedomain.com/afile.jsp?param1=xx&param2=yy"

Hi, I am trying to fit a logarithmic trendline to a scatterplot of a species accumulation curve. I've tried abline, lines, curve and scatter.smooth but none of these work. Can anyone help please, Kyran

Is there any way to include warnings in the output from capture.output? eg: a <- capture.output(warning("test")) all.equal(a, "Warning message: \n test ") Conceptually, this seems like redirecting stderr to stdout, or somehow changing warning to simple print it's output. I've had a look at tryCatch and using a warning handler, but this terminates execution at the
