Constrain density to 0 at 0?
I'm plotting some trip length frequencies using the following code:
plot( density(zTestData$Distance, weights=zTestData$Actual),
    xlim=c(0,10),
    main="Test TLFD",
    xlab="Distance",
   col=6  )
lines(density(zTestData$Distance, weights=zTestData$FlatWeight), col=2)
lines(density(zTestData$Distance, weights=zTestData$BrdWeight ), col=3)
which works fine except the distances are all positive, but the densities don't drop to 0 until around -2 or -3.
Is there a way for me to "force" the density plot to 0 at 0?
Thanks

After writing data in MMF using SEXP structure, can i reference in R?
