rescale {ggbio}R Documentation

rescale ggplot object

Description

Rescale a numeric vector or ggplot object, could be used for static zoom-in in ggbio.

Usage

## S4 method for signature 'numeric'
rescale(x, to = c(0, 1),
      from = range(x, na.rm = TRUE))

## S4 method for signature 'ggplot'
rescale(x, xlim, ylim, sx = 1, sy = 1)
## S4 method for signature 'gg'
rescale(x, xlim, ylim, sx = 1, sy = 1)

Arguments

x

A numeric object or ggplot object to be rescaled.

to

For numeric object. it's a vector of two numeric values, specifying the range to be rescale.

from

Range of x.

xlim

For ggplot object. This specify the new limits on x-scale.

ylim

For ggplot object. This specify the new limits on y-scale.

sx

Scale fold for x-scale. Default is 1, no change.

sy

Scale fold for y-scale. Default is 1, no change.

Details

When x is numeric value, it's just call scales::rescale, please refer to the manual page to check more details. If x is ggplot object, it first try to estimate current x limits and y limits of the ggplot object, then rescale based on those information.

Value

Return the object of the same class as x after rescaling.
