I am encountering below error while running BiodiversityRGUI() in R. Please see below error message:

> library(BiodiversityR)
Loading required package: tcltk
Loading required package: vegan
Loading required package: permute
Loading required package: lattice
This is vegan 2.4-1
BiodiversityR 2.7-2: use function 'BiodiversityRGUI()' to launch the BiodiversityR Graphical User Interface

  error: [tcl] Invalid state name hover.

Error: package or namespace load failed for 'Rcmdr'

I know that the error is because of missing dependency 'Rcmdr'. I had already tried installing the same. Any guesses?
