R package for a simple (but visually enchanting) Pivot table?

Hello,

Task: Create an simple visual showing users occupancy each day in the form of a Pivot table (see attachment).

Measures: Hours

Dimensions: Users and Date

Limitations: Haven't found a visual in PBI both standard as well as custom visuals that can show it in this way.

Question: I was wondering if someone knew a simple package to install in RGUI so that I can create a similar visual?

Frankly, can someone point me in the right direction?
