When coupling several function calls with the pipe-operator, the benefit will become more apparent. Consider this pseudo example:
WebbThe pipe operator takes the left-hand side (LHS) of the pipe and uses it as the first argument of the function on the right-hand side (RHS) of the pipe. For example: library (magrittr) 1:10 %>% mean # [1] 5.5 # is equivalent to mean (1:10) # [1] 5.5. The pipe can be used to replace a sequence of function calls.
