[R] list indexing problem reading in files from a directory

I am running into a problem with allocating these files to a list as
they are read in through a for loop.  I know I am probably doing
something wrong, but I can't figure out what.  I know this is not
reproducible.  I am ending up with a data frame of the very last file
to be read in.  I know it is in the indexing, but I can't wrap my head
around it.
thanks for all of the help,
