Last Updated: Mar 11, 2023

Description#

Plot distribution of intensity values using either a density plot or a histogram. Useful for finding image artefact outliers and determining reasonable scaling cutoffs.

Usage#

distGiottoImage(
  gobject = NULL,
  image_type = "largeImage",
  image_name = NULL,
  giottoLargeImage = NULL,
  method = c("dens", "hist")
)

Arguments#

`gobject`	giotto object
`image_type`	image object type (only supports largeImage and is set as default)
`image_name`	name of image object to use
`giottoLargeImage`	giotto large image object
`method`	plot type to show image intensity distribution

Details#

Plot is generated from a downsampling of the original image

Plotting method `'dens'`#

Density plot of intensity values for image objects. N total values examined. Bandwidth refers to the curve smoothing value applied.

Plotting method `'hist'`#

Histogram of intensity values for image objects.
