[R] Converting 16-bit to 8-bit encoding?

Hello all-

I have a question related to encoding. I'm using a seperate program which takes either 16 bit or 8 bit (flat binary files) as inputs (they are raster satellite imagery and the associated quality files), but can't handle both at the same time. Problem is the quality and the image come in different formats (quality- 8bit, image- 16bit). I need to switch the encoding on the quality files to 16 bit, without altering anything else (they are img files right now). I imagine this is a fairly simply process, but I haven't been able to find a package or anything which can tell me how to do it- perhaps I'm searching the wrong terms, but I did look. Is there any methods to do this quickly? Ideally, the solution would involve reading in a list of files and replacing the original with the new, 16 bit version, as I have over 300 files to convert. I hope that's clear. Thanks in advance!
