This is a direct replacement for [[.data.frame.

pull(.data, var = -1)

Arguments

.data

A data.frame.

var

A variable specified as:

  • a literal variable name

  • a positive integer, giving the position counting from the left

  • a negative integer, giving the position counting from the right

The default returns the last column (on the assumption that's the column you've created most recently).
