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

[1] 4pt 0pt 0pt 0pt
margin(4, 2)
[1] 4pt 2pt 0pt 0pt
