Dear Oscar,
The problem has to do with rounding (because you set the global digits
value to 2). Although what you see is 2.4*270=670; when R actually
calculates it, it is using full precision. If you set
options(digits=7) # the default
you will see that AR=2.357362, not 2.4.
HTH,

Dear Rxperts,
Running the following code:
===
twlo=10; twhi=20; wt=154; vd=0.5; cl=0.046; tau=6; t=3; F=1;
wtkg <- wt/2.2 # convert lbs to kg
vd.pt <- wtkg * vd # compute weight-based vd (L)
cl.pt <- wtkg * cl # com
