Hi, I have a problem with widgetTools 1.8.0 and R 2.3.0. I get an error message executing the example code of the widget function: > example("widget","widgetTools") ..as stated in the help the last line of code of this example has to be pasted interactively in the R console: > aWidget <- widget(wTitle = "A test widget", pWidgets, funs = list(),preFun = function() print("Hel lo"),postFun = function() print("Bye"), env = PWEnv) [1] "Hello" Error in validObject(.Object) : invalid class "widgetView" object: class for slot "winid" ("tkwin") ..and the widget obviously does not appear. I did not get this error with R-2.2.0 and bioC 1.7, while I have got it in both linux and Windows R-2.3.0, bioC 1.8, widgetTools 1.8.0 This is the sessionInfo for linux: > sessionInfo() Version 2.3.0 (2006-04-24) x86_64-unknown-linux-gnu attached base packages: [1] "tcltk" "methods" "stats" "graphics" "grDevices" "utils" [7] "datasets" "base" other attached packages: widgetTools "1.8.0" thanks for any suggestion Mattia -- Mattia Pelizzola PhD Student Genopolis Consortium Milano-Bicocca University P.zza della Scienza 4 20126 Milano (Italy) tel:+390264483556 fax:+390264483552

Jianhua, has sent in a fix for this. A patched version of widgetTools, version 1.8.1, will be available within a few days in the Bioc 1.8 package repository. Best, + seth
