[R] Mixing lty specifications in legend

[Peter Dunn]

Hi all

I have a plot with lines, one specified as (say) lty=1, 
using standard line types, and another as (say) my
own spec: lty="51".

I can't get  legend  to display both.  Toy example:


> plot(1~1)
> legend("topright", lty=c("51",1), legend=c("My own","Standard"))
Error in segments(x1, y1, x2, y2, ...) : invalid line type: must be
length 2, 4, 6 or 8

Any ideas?
