I've written a script in R using the gWidgets library. It works perfectly when I copy and paste the script into R, but it's failing mid-execution when executed using
./myscript.r
in the linux terminal with an error message
Error in (function (classes, fdef, mtable) : unable to find an inherited method for function ‘.gwindow’ for signature ‘"NULL"’ Calls: gwindow -> .gwindow ->
I used the gwindow function once in the script as this:`
win <- gwindow("Diary", horizontal = FALSE, visible=TRUE, height = 1000)
So, I'm asking, why do I have an error message for 'signature "NULL"' ?
