Select Regions of an Imaging Dataset

Description

Manually select regions-of-interest or pixels on an imaging dataset. This uses the built-in locator function. The method has the same form as the image method for plotting imaging datasets.

Usage

## S4 method for signature 'SImageSet'
select(x, formula = ~ x * y,
    mode = c("region", "pixel"),
    ...,
    main,
    subset = TRUE,
    lattice = FALSE)

Arguments

`x`	An imaging dataset.
`formula`	Passed to `image`.
`mode`	What kind of selection to perform: 'region' to select a region-of-interest, or 'pixel' to select individual pixels.
`...`	Addtional arguments to be passed to `image`.
`main`	Passed to `image`.
`subset`	Passed to `image`.
`lattice`	Must be false.

Value

A logical vector of length equal to the number of pixels.
