r - gWidgets - ginput() function error -

-



i'm having problem launching ginput pop-up gwidgets.

this error:

loading required package: gwidgetstcltk error in (function (classes, fdef, mtable) : unable find inherited method function ‘.ginput’ signature ‘"guiwidgetstoolkittcltk"’ in addition: warning message: in library(package, lib.loc = lib.loc, character.only = true, logical.return = true, : there no package called ‘gwidgetstcltk’

i use popup type number assign variable.

code snippet follows:

options(guitoolkit = "tcltk") # tool kit dependency gwidgets. library(gwidgets) # package required launch ginput gui.  width.var <- as.numeric(ginput("enter value - width        ",                                title = "png dimensions",                                 icon = "info"))

supplementary info:

i updated r version 3.2.5 3.4.1 installing latest rstudio version. i've run code section before on r3.4.1 on different computer without issues.

right suspect it's rstudio don't know how fix it.

any appreciated.

i fixed installing "gwidgetstcltk". assumed because load tcltk , gwidgets separately enough. alex
