You can create your own dashed lines:

lty
The line type. Line types can either be specified as an integer
(0=blank, 1=solid (default), 2=dashed, 3=dotted, 4=dotdash,
5=longdash, 6=twodash) or as one of the character strings "blank",
"solid", "dashed", "dotted", "dotdash", "longdash", or "twodash",
where "blank" uses 'invisible lines' (i.e., does not draw them).

_Alternatively, a string of up to 8 characters (from c(1:9, "A":"F"))
may be given, giving the length of line segments which are
alternatively drawn and skipped. See section 'Line Type
Specification'_
