How to Define the Operator %% in R

Overview

In R, it is possible to define a function as a binary operator right away. The remainder operation %%, the quotient operation %/%, dot product %*%, %o% or inclusion %in%, and the pipe operator %>% that are already defined in R also belong to these binary operators.

Code

For instance, in a language like Python, adding strings together concatenates them, which is very convenient, but R is somewhat inconvenient in comparison. Considering binary operators as a solution to this could be helpful.

"%++%" <- function(x,y) {paste(x,y)}
 
example <- "Oh" %++% "My" %++% "Girl"
print(example)
