Add a "line type" (lty) argument ?

[HuguesPecout]

It would be nice to be able to modify the line type (as the "lty" argument for the plot function). This would be particularly useful for 'typo' maps applied on lines.

Can you be a bit more specific on your needs? Should it be equivalent to pch for "symb" maps but used when input are lines?

This already works with "base" type. I'll think about how to use it in other types.
