[R] R does not subset

This typically occurs because of sloppy manual data entry outside of R. To
relieve further analysis pain, you can manually clean the data (usually only
effective for one-time analyses) or use R to fix problems right after
loading the data (there are multiple methods for doing this... I prefer
using ?sub on character data before creating the factor).

str_trim in package stringr is great for this.
