Subset by x- and y-range

Creates a subset of the original SPATA2 object based on x- and y-range. Barcode-spots that fall into the rectangle given by xrange and yrange are kept.

cropSpataObject(object, xrange, yrange, verbose = NULL)

Arguments

object

An object of class spata2.

xrange, yrange

Vector of length two or NULL. If not NULL, specifies the x- and y-range to which the output image is cropped. E.g. xrange = c(200, 500) results in the image being cropped from x-coordinate 200px up to x-coordinate 500px. If NULL, the original image ranges are taken.

This argument works within the SPATA2 distance framework. If values are specified in European units of length the input is immediately converted to pixel units. See info section Distance measures for more information.

verbose

Logical. If set to TRUE informative messages regarding the computational progress will be printed.

(Warning messages will always be printed.)

Value

The input spata2 object containing the added or computed results.
