scenarios Handling in R with 'tryCatch' - Why is my warning not captured?
I'm testing a new approach and Quick question that's been bugging me - Could someone explain Quick question that's been bugging me - I'm not sure how to approach I've been banging my head against this for hours..... I'm currently using R version 4.2.1 and trying to implement robust behavior handling in my script using the `tryCatch` function. Specifically, I want to capture warnings as well as errors, but I'm running into an scenario where my warning messages are not being captured as expected. Here's a simplified version of my code: ```r my_function <- function(x) { if(x < 0) { warning('Value is negative!') } return(sqrt(x)) } result <- tryCatch({ my_function(-1) }, behavior = function(e) { cat('behavior:', e$message, '\n') }, warn = function(w) { cat('Warning:', w$message, '\n') }) ``` When I run this code, I expect to see the warning message captured in the console. However, the warning is printed directly to the console instead of being caught by `tryCatch`. I've also tried suppressing the warning using `suppressWarnings()`, but it doesn't help in capturing it through `tryCatch`. I’ve looked through the documentation and common practices but still can’t figure out why the warning is not being captured as intended. Has anyone encountered a similar scenario or know how to properly capture warnings in this context? Any insights would be greatly appreciated! Thanks in advance! What are your experiences with this? Is there a simpler solution I'm overlooking? Hoping someone can shed some light on this. I've been using R for about a year now. Any suggestions would be helpful. I'm on Debian using the latest version of R. Thanks, I really appreciate it!
