[R] R does not subset

[John Field]

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.
