[R] Question concerning Loading large Data Sets

[Spencer Brackett]

Also,

In case there is any confusion... "~/Vakul's GBM code" was set up in the
working directory (via setwd) as the folder in which the file 'mapper.txt'
is contained... thereby making the "~/Vakul's GBM code/mapper.txt" as
shown.

Should I perhaps reset my working directory to the file I'm trying to
access, exclusively?
