Hi guys so I’m about 800 miles in with my new R1 rotors and centric pads, but I keep getting squeals when I come to a stop. Anyone know why this would be happening? I installed them straight from the box (using brake cleaner on the rotors before installing). It didn’t squeal on the first day driving it, but it started on the second day and is on and off....

Did you do a proper break in procedure?? The brake pads need to "bed in" (brake pad material to bond to the brake rotor) properly for brakes to work efficiently.
The procedure I use for all my cars from my daily drivers to my high horsepower "play" cars are as following....

5 moderate to aggressive stops from 40 mph down to 10 mph in rapid succession without letting the brakes cool and do not come to a complete stop. If you’re forced to stop, either shift into neutral or give room in front so you can allow the vehicle to roll slightly while waiting for the light. The rotors will be very hot and holding down the brake pedal will allow the pad to create an imprint on the rotor. This is where the judder can originate from.

Then do 5 moderate stops from 35 mph to 5 mph in rapid succession without letting the brakes cool. You should expect to smell some resin as the brakes get hot.

After this is complete, drive around for as long as possible without excessively heating the brakes and without coming to a complete stop (Try for about 5 minutes at moderate speed). This is the cooling stage. It allows the heated resin in the brake pads to cool and cure.

After the brakes have cooled to standard operating temperature, you may use the brakes normally.

If you didn't brake in the pads correctly, I would take the rotors to a shop to have it resurfaced. Then do a correct break in procedure. Also make sure you use brake grease to lube up all metal contact sliding parts.
