In some computing subcultures, the term “grapes” refers to the percent sign, which R uses to name binary operators such as %*%. The grapes package in R constructs such operators out of arbitrary functions. As with the magrittr pipe, this could help you avoid cumbersome parentheses in your code.

grow(rbind, c, from = "base") # `from` names a package or environment to search.
bunch() # see the operators (grapes you have grown)
nrow(sleep) # 20
longer = sleep %rbind% sleep %rbind% sleep # No clumsy parentheses!
nrow(longer) # 60. Many of us would like to sleep longer.
1 %rbind% 2 %c% 3
