[R] Adding Year-Month-Day to X axis

[Jim Lemon]

Hi Greg,
This is because both plots have equally spaced x values. To see the
difference, try this:

plot (x_yyyymmdd, y_duration, type="l", xaxt="n", yaxt="n",
ylim=range(240,480), xlab="", ylab="", col="blue")
axis(1)
plot (            y_duration, type="l", xaxt="n", yaxt="n",
ylim=range(240,480), xlab="", ylab="", col="red" )
axis(1)
