R: Set Plot Margins

Mar {DescTools}

R Documentation

Set Plot Margins

Description

Plot margins are normally set by par("mar"). However one is forced to define all margins, even if just one should be altered. This convenience function allows to set one single margin (or several) while leaving the others unchanged.

Usage

Mar(bottom = NULL, left = NULL, top = NULL, right = NULL, outer = FALSE)

Arguments

`bottom`	the bottom margin, if set to `NULL` the current value will be maintained.
`left`	the left margin, if set to `NULL` the current value will be maintained.
`top`	the top margin, if set to `NULL` the current value will be maintained.
`right`	the right margin, if set to `NULL` the current value will be maintained.
`outer`	logical, defining if inner margins (`par("mar")`) or the outer margins (`par("oma")`) should be set. Default is FALSE, meaning that the inner margins will be concerned.
