I want to save the my tab delim files manually. I mean that I want user to choose the directory and file name when he wants to save the data. (For an example I have merged individual files into single file and want to save it.)
Usually I use
Annoyingly the tcltk package doesn't have a function for 'Save As', it only has a file selector for choosing an existing file.
Luckily you can take the DIY approach via some tcl calls:
require(tcltk) write.table(yerdata,file = tclvalue(tcl("tk_getSaveFile")))
tk_choose.files function source could be used as a template to write a nicer interface to tcl("tk_getSaveFile") if needed. Does seem to be a glaring omission in package:tcltk though...
