slice_colour_df

Slice a Image Color Data.frame

Slices a image color data.frame along the 3 planes (axial, coronal, sagittal) and returns it in a ggplot-ready format for faceting.

slice_colour_df(img_df, xyz = NULL)

`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

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))
