I wouldn't use grid - it suggests you try abline, so something like:

 > abline(v=my.data$date,lty=2)

 - to put vertical lines at your data points. For the horizontal grid
lines, we can just use the axis tick marks:

 > axTicks(2)
 [1] -5  0  5 10 15 20

 thus:

 > abline(h=axTicks(2), lty=2)

adjust lty and col options to suit
