问题
Why is there no tutorial online about replicating R's basic cor() function in tableau. All I can find are tutorials to visualize correlations of values by dimension. I just want to see how all variables in my data are correlated to each other.
And thanks for the support @user1036719

All,
I have figured out the simplest way to solve my own problem. With the introduction of Tableau 9.0, you can load .RData files directly into Tableau. Here is how you go about it:
1) Simply save() your correlation matrix as an .RData file. 2) Connect Tableau to the .RData file 3) Put "Measure Names" in the Columns field & "Rownames" in the Rows field. 4) Set Marks from "Automatic" to "Square" 5) Drag "Measure Values" over the "Color" Marks category
Voila! You're done. With the new R integration this is so much simpler than any solution I have found online.
