getPixelDf: Obtain pixel data.frame
In kueckelj/SPATA2: A Toolbox for Spatial Gene Expression Analysis
getPixelDf R Documentation
Obtain pixel data.frame
Description
Extracts a data.frame in which each row corresponds
to a pixel in the current image with x- and y-coordinates.
Usage
getPixelDf(object, xrange = NULL, yrange = 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.
Value
Data.frame with nrow() equal to the number of pixels.
