Hello,

Something wrong happens when I use the seq (function). Here it is an exampl=
e from my R console, I have the R version 2.7.2 (2008-08-25) running on Mic=
rosoft windows XP Version 2002 Service Pack 3, and my machine is a Dell Opt=
ilex GX280 with a processor Intel Pentium 4 CPU 2.80GHhz, 0.99 GB RAM:

>r=3Dseq(0.150,0.180,0.001)

=20

> r[16]

=20

[1] 0.165

> class(r[16])

=20

[1] "numeric"

> for (i in (150:180)/1000)

Could you explain me why from the 16th element to the 22nd the value is int=
eger (0)  ? I really don't understand... so it would be very nice of you to=
 do it.
