Can not load package tcltk in R [duplicate]

Question

I am trying to do multiple imputation in R and have installed Amelia and tried to open AmeliaView but it said require tcltk package. I proceeded to install tcltk but error message pop out as follows. Could someone help me?

> AmeliaView()
Loading required package: tcltk
Loading Tcl/Tk interface ... Error : .onLoad failed in loadNamespace() for 'tcltk', details:
  call: dyn.load(file, DLLpath = DLLpath, ...)
