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)?
By convention, NA's say to break the lines, so remove the NA's.
okay <- !is.na(x) & !is.na(y)
lines(x[okay], y[okay])
