Examples

 x1 = seq(-3, 3, by = 0.1)
 y1 = dnorm(x1)
 x2 = seq(-5, 1, by = 0.1)
 y2 = dnorm(x2, mean = -1)
 data = data.frame( x = c(x1,x2),
                    y = c(y1,y2), 
                    col = c(rep("ok", length(x1)), rep("shifted", length(x2))), 
                    ltype = c(rep("solid", length(x1)), rep("dotted", length(x2))))
