How can I get the \vector command to print a bigger arrow under LaTex?

Thank you!

The \vector command works within a picture environment and it gives a
vector as long as you wish. Compile this document:

\documentclass{article}
\begin{document}
\begin{picture}(100,100)(0,0)
\put(0,0){\vector(1,1){25}}
\put(0,15){\vector(1,1){50}}
\end{picture}
\end{document}

for instance, and you will see two vectors, one of which is twice as
long as the other one.

Thank you for the reply. My problem is not the length of the vector,
by the size of the arrowhead. :-) Is there a way to make only the
arrowhead bigger?

Thank you

The reason I need a bigger arrow, is that my document will be
photocopied, and I am just afraid that the arrows might not photocopy
correctly.

perhaps you want to switch to a comprehensive vector graphics package
like PSTricks or TikZ, or to an external vector graphics program like
Asymptote or MetaPost. With LaTeX's builtin drawing capabilities only
very basic drawings are possible.
