plot_low_res {PersomicsArray}

plot_low_res

Description

This function generates low resolution plots of pixel values stored in arrays, and is called by function spot_id.

Usage

plot_low_res(plot.image=NULL, rescale.factor=1000, add=FALSE,
pallete=gray.colors(20),main=NULL)

Arguments

plot.image

Array-type object containing image data.

rescale.factor

Numeric value specifying the fold reduction of resolution from original image. Larger values make the function run faster, but at the cost of image resolution.

add

If TRUE, adds the plot to the current active device. If FALSE, a new plot is generated.

pallete

Specifies the color pallete to be used for generating the plot.

main

Character string containing the plot title.
