Hi, I found this issue:
when I have 3 modules: * AnalysisA * AnalysisB * AnalysisC I load all modules at the beginning from list of modules: analyses <- list('AnalysisA', 'AnalysisB', 'AnalysisC') for (module in analyses) { library(module, character.only = TRUE) } and I want to add a function isValid to each module, but I've added it only for AnalysisB. When I run this code: # value <- <selected by user> flags <- sapply(analyses, function(module) { namespace <- getNamespace(module) tryCatch({ isValid <- get("isValid", namespace) isValid(value) }, error = function(e) { TRUE }) }) # show analyses analyses[flags] then when R call get for AnalysisA it throw error, for AnalysisB it return function but for AnalysisC it return function from AnalysisB and don't throw error. As a workaround instead of tryCatch I've used: if ("isValid" %in% ls(namespace)) { isValid <- get("isValid", namespace) isValid(value) } else { TRUE } Is this a bug? Should this be reported? I'm using R 3.4.0 on windows. -- Jakub Jankiewicz, Web Developer http://jcubic.pl/me ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
