Hey, I don't use Nikon gear, so this may or may not apply...
But many Canon DSLRs (incl. some I've used) have both the "standard" and a number of more automated modes on the same "mode" dial. Setting the camera to A/Av, S/Tv, M or P mode allows you to freely change the type of file that's saved. But if you use A+/Auto ("point n shoot" mode) or any of the "Scene modes" such as "sports", "landscape", etc. those will ONLY ALLOW JPEG files to be saved (these modes also generally dictate the AF setup, picture style settings, possibly the white balance and more). Those are essentially "super auto" modes, waaayyy more than just "auto exposure".
Are Nikon similar? If so, for some of those shots where no RAW was recorded, did you use a mode that only allows certain types of files to be saved?
Using some other in-camera features also might prevent saving a RAW file. For example, HDR and multiple exposure modes are "JPEG only" in a lot of cameras I've seen.
P.S. I just looked at a photo of a D7100 and see the dial on the LH shoulder has Auto, Scene and Effects options.... Switching to any of those for a few shots might cause a change in the type of file that's saved. Check the manual... you might only be able to save RAW files in the M, A, S and P modes (same as Canon).

BINGO! I just tried, and sure enough, my nose pushed the button. And, when I used the thumb wheel, it cycled thru all the options. Duh! It was very easy to change from RAW to something else. And, would explain why I had such a random mix. THANKS!šš¤š
Sounds like you might have found the problem. If so, great! Does the Nikon D7100 allow you to change button assignments? Maybe you can prevent that from happening again.
