I have some data (REE plots - geochemistry) where I have values 1:14 for the
x axis, but have no data for some x values.  Here for example, let's say
that I don't have data for x=2,5,8.

So

x<-1:14
y<-c(4, NA, 5, 9, NA, 3.4, 8, NA, 19, 22, 12, 14, 15.3, 15)

if I plot the data

plot(x,y)

and then I want to join with lines

lines(x,y)

How do I get it so the points join across the missing x-values?  So the line
joins, for example, point 1,4 with point 3,5  (i.e across point 2,NA)?

Thanks in advance.
