trim {gridGeometry}

Generate Subsets of Coordinates

Description

This functions generates a new set of coordinates by subsetting a set of coordinates.

Usage

trim(x, from, to, ...)
## S3 method for class 'grob'
trim(x, from, to, rep=FALSE, ...)
## S3 method for class 'gPath'
trim(x, from, to, rep=FALSE,
                     strict=FALSE, grep=FALSE, global=FALSE, ...)
## S3 method for class 'character'
trim(x, from, to, rep=FALSE,
                         strict=FALSE, grep=FALSE, global=FALSE, ...)

Arguments

x

A set of coordinates. Or a grob, or a gPath (or a character value) identifying a grob that has already been drawn from which coordinates are generated.

from

A numeric vector or a unit object describing the start point of each subset.

to

A numeric vector or a unit object describing the end point of each subset.

rep

A logical value indicating whether the from and to values should be repeated to consume the entire line.

strict, grep, global

Arguments controlling the interpretation of the gPath (passed to grid.get).

...

Arguments used by methods.

Value

A new set of coordinates.
