Compound inequalities in R

It's sometimes cumbersome to perform a comparison to see if x is between two other values. The functions in this project create compound inequality operators---%>>%, %>>=%, %<<%, and %<<=%---that make it easy to specify comparisons that are inclusive or exclusive on either side, while only typing the compared variable names once.

Examples

3 %<<=% 3 %<<=% 5
# TRUE

3 %<<% 3 %<<=% 5
# FALSE
