buffer_area: Buffer area

In theMILOlab/SPATA2: A Toolbox for Spatial Expression Analysis

Buffer area

Description

Buffers the area of a polygon.

Usage

buffer_area(df, buffer, close_plg = TRUE, cvars = c("x", "y"))

Arguments

df	Data.frame with variables x and y describing the vertices of the polygon that encircles the area based on which the barcode-spots are binned. E.g. slot @area of SpatialAnnotation-objects. Note that the order of observations in the data.frame must correspond to the order of vertices of the polygon.
buffer	The distance by which to consecutively expand the area that covers the spatial annotation screening. Given to argument dist of function sf::st_buffer().
cvars	Character vector of length two. The variable names that correspond to the x- and y-coordinates.
