In wlandau/grapes: Make Binary Operators

In some computing subcultures, the term "grapes" refers to the percent sign, which R uses to name binary operators such as %*%. Here, grapes is an R package that turns arbitrary functions into binary operators. As with the magrittr pipe, this allows you to avoid cumbersome parentheses in your code.

library(grapes)
grow(rbind, c, from = "base") # Use `from` to specify 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. Most of us would like to sleep longer.
1 %rbind% 2 %c% 3
