Description

This is a list of matricies where each matrix represents a design for drawing lines on the face of a coin.

Usage

data(coin.faces)

Format

The format is: List of 4 $ qh: num [1:57, 1:2] 0.387 0.443 0.515 0.606 0.666 ... $ qt: num [1:62, 1:2] 0.862 0.873 0.875 0.857 0.797 ... $ H : num [1:28, 1:2] 0.503 0.506 0.548 0.548 0.500 ... $ T : num [1:18, 1:2] 0.506 0.520 0.569 0.626 0.626 ...

Details

The current options are a capitol "H", a capitol "T", a design representing George Washingtons head traced from the heads of a US quarter, and a design representing an eagle traced from the tails of a US quarter.

The tracings here have pretty much exhausted my artistic ability, if you can do better, please do, I will be happy to include it in future versions. It would also be nice to include some designs representing faces of non-US coins, please submit your contributions (the design should fit within a circle inscribed within the unit square).

Examples

if (FALSE) {
plot.rgl.coin(heads=coin.faces$H, tails=coin.faces$T)
}
