Rescale Kandinsky polygon xy coordinates

Apply a shift or a scaling factor to either one or both x and y polygon coordinates stored in Kandinsky sf slot

scale_coords(seurat, xfact = NULL, yfact = NULL, fun = c("*", "+", "/", "-"))

Arguments

seurat

a Seurat object containing Kandinsky data (KanData())

xfact

numeric value, shifting or scaling factor to apply to x coordinates. Default value is 0 for shifting, and 1 for scaling transformations

yfact

numeric value, shifting or scaling factort o apply to y coordinates. Default value is 0 for shifting, and 1 for scaling transformations

fun

character indicating the operator to use for coordinate transformation. Must be one of the following: "*": multiply x/y coordinates by xfact/yfact (scaling) "+": add xfact/yfact to x/y coordinates (shifting) "/": divide x/y coordinates by xfact/yfact (scaling) "-": subtract xfact/yfact to x/y coordinates (shifting)

Value

Seurat object with updated polygon coordinates in Kandinsky sf slot
