Examples

# Basic use:
iris %>% head

# Use with lhs as first argument
iris %>% head(10)

# Using the dot place-holder
"Ceci n'est pas une pipe" %>% gsub("une", "un", .)

# When dot is nested, lhs is still placed first:
sample(1:10) %>% paste0(LETTERS[.])

# This can be avoided:
rnorm(100) %>% {c(min(.), mean(.), max(.))} %>% floor

# Lambda expressions:
iris %>%
  {
    size <- sample(1:10, size = 1)
    rbind(head(., size), tail(., size))
  }

# renaming in lambdas:
iris %>%
  {
    my_data <- .
    size <- sample(1:10, size = 1)
    rbind(head(my_data, size), tail(my_data, size))
  }
