[R] Need help with renaming sub-directories and its files after attribute vales from a shapefile

Hello, Keep in mind I am VERY new to using R... What I am trying to do is package hundreds of files into a new sub-directory. I was able to accomplish this with the code below. HOWEVER, I have come to find that instead of merely having to name the new sub-directory after the 7-digit numeric prefix
