Usage

slice_colour_df(img_df, xyz = NULL)

Arguments

img_df	an image data.frame, usually from img_colour_df. Must have the columns: dim1, dim2, dim3, colour, and value.
xyz	coordinates to slice the data.frame in x, y, and z - domains

Value

A data.frame with x and y coordinates, colour, and intensity values, along with the associated planes that were sliced.

img = nifti(array(rnorm(10^3), dim = rep(10, 3)))
df = img_colour_df(img)
sliced = slice_colour_df(df, c(5, 5, 4))
