using attach/with vs pipes

[Mohamed_Fergany]

Hi everyone,

A quick question if I may. when dealing with data when it's better to use attach and/or with rather than pipes.

Thanks

Attach makes the variables contained in the data available by their names

Take an example here

data("cars")
names(cars)

First attach the data to make the variables available as R object(s)

attach(cars)

Now call variables directly

head(Price, 2) ; head(Mileage, 2) ; head(Cylinder, 2)

When using pipe you will need to refer to the data frame containing your data

and it is best used with some supporting libraries (dplyr/tidyverse)

cars |> dplyr::select('Price') |> head(2)
