image2data - Turn Images into Data Sets
The goal of 'image2data' is to extract images and return
them into a data set, especially for teaching data manipulation
and data visualization. Basically, the eponymous function takes
an image file ('png', 'tiff', 'jpeg', 'bmp') and turn it into a
data set, pixels being rows (subjects) and columns (variables)
being their coordinate positions (x- and y-axis) and their
respective color (in hex codes). The function can return a
complete image or a range of color (i.e., contour, silhouette).
The data can then be manipulated as would any data set by
either creating other related variables (to hide the image) or
as a genuine toy data set.
