 #Install RGtk2 Locally (I left in in my downloads folder) from the following link:
 #https://cran.r-project.org/bin/windows/contrib/3.3/RGtk2_2.20.31.zip 

 #Install RGtk2 into RStudio from the local file with the function arguments repos=NULL and type = "win.binary": 

 >install.packages("FILEPATH", repos = NULL, type = "win.binary")

 #Install Rattle, including dependencies:

 >install.packages("rattle", dep=TRUE)

 #Close R Studio
 #Re-open R Studio

 #Call Rattle as you would:

 >library(rattle)
 [Rattle launch message]
 >rattle()

 Rattle should launch normally.

 PLEASE NOTE:

 R may prompt you to install Gtk+ in a small window after the first time you close out of R Studio and go back into R Studio to launch Rattle. You have no choice but to say (and this is okay). 
 It will throw an error message "Could not download Rgt+ dynamic package" (or something similar ). THIS IS OKAY.
 R prompts us to do this automatically with the Rattle version taken from CRAN. This was the root of the actual issue: the current version of Rattle auto-installs an RGtk2 version that is buggy. By failing to install the dynamic Rgt+ package, R throws the error message "error in root..."requires" because of the failed package install. We will bypass this bad version of Rgt+ (the version without the dynamic library) in the next step because we installed a complete version of RGtk2 directly from a local file and not the CRAN version.

 Close out of R Studio again, and re-open. This time, to launch Rattle, use the require() function on Rgtk2 to pre-load the CORRECT version of Rgtk2 we downloaded in the first step of the original post. This will bypass the incomplete Gtk+ package that R forces you to install. It should look like this:

 > require(RGtk2)
 Loading required package: RGtk2
 > library(rattle)
 Rattle: A free graphical interface for data mining with R.Version 4.1.0 Copyright (c) 2006-2015 Togaware Pty Ltd.Type 'rattle()' to shake, rattle, and roll your data.
 > rattle()

 This will launch a fully functional version of Rattle because we installed and then pre-loaded the correct RGtk2 package.
 FINAL NOTE: To avoid error messages OR loading an incomplete version of Rattle (where the GUI pops up), get in the habit of calling >require(RGtk2) before the commands to launch Rattle.
