This is a convenient function that creates a grid unit object of the correct length to use for setting margins.

Usage

margin(t = 0, r = 0, b = 0, l = 0, unit = "pt")

Arguments

t, r, b, l

Dimensions of each margin. (To remember order, think trouble).

unit

Default units of dimensions. Defaults to "pt" so it can be most easily scaled with the text.

Examples

margin(4)
#> [1] 4points 0points 0points 0points
margin(4, 2)
#> [1] 4points 2points 0points 0points
margin(4, 3, 2, 1)
#> [1] 4points 3points 2points 1points
