library(pido)

1:4 %map% (num ~ num^2) # first variant
1:4 %map% (~ num^2) # another variant
1:4 %map% (~ .^2) # third

is equivalent of

1:4 %>% map(~ x^2) # in dplyr

sapply(1:4, function(x) x^2) # or without packages

list(c(1, 2), c(2, 3)) %map% (first ~ second ~ first * second) # first
list(c(1, 2), c(2, 3)) %map% (~ x * y) # and second variant

is equivalent of

sapply(list(c(1, 2), c(2, 3)), function(x, y) x * y)

list(c(1, 2), c(2, 3)) %map% (~ {
    dbl <- x * 2
    trpl <- y * 3
    return (dbl + trpl)
})

this code will work correctly and will be equivalent of

sapply(list(c(1, 2), c(2, 3)), function(x, y) {
    dbl <- x * 2
    trpl <- y * 3
    return (dbl + trpl)
})

PIDO abbreviation stands for it.
