Graphics device for ASCII output

Graphics primitives will be rendered using ASCII characters.

ascii(filename = NULL, width = NULL, height = NULL, font_aspect = 0.45, ...)

Arguments

filename	If given, write ascii to this file, otherwise write to console.
width, height	dimensions of text output (in characters). Default: NULL (auto-detect)
font_aspect	Character spacing horizontally and vertically are almost never the same. On many terminals character resolution vertically is half the resolution horizontally. Adjust this value if circles don't look right. Default: 0.45
