Jack,
in R : is an ordinary function with two arguments, ie. 1:10 is a function
call with arguments 1 and 10. This way at the time : is evaluated the
variable which will be indexed is not known; it is thus impossible to know
its length. This is why it is not easy to implement end in R.
Since R

Hi WizaRds,
In MATLAB you can do
x=1:10
and then specify
x(2:end)
to get
2 3 4 5 6 7 8 9 10
In R you could do the above via:
x[-1]
or whatever (note that in MATLAB the parenthetic index notation is used, not
brackets as in R).
Hi WizaRds,

index point of the array.
Obviously there
