# [R] Arrow heads at the end of axes

Thu Oct 21 14:12:52 CEST 2004

I would like to have arrow heads at the end of my axes, since I am
plotting variable where the absolute amount is irrelevant, there is not
supposed to be numbers on the axes.

An imperfect example:
plot(rnorm(10),bty='l',xaxt='n',yaxt='n',ylab='',xlab='',type='l')
abline(h=0)

Like this but without, the xaxis and with arrrowheads

More like this in fact,
LaTeX Picture example:

\setlength{\unitlength}{1.3cm}
\begin{picture}(4.3,3.6)(-2.5,-0.25)
\put(-2,1.8){\vector(1,0){4.4}}
\put(2.5,1.7){$x$}
\put(-2,0){\vector(0,1){3.2}}
\put(-2,3.35){\makebox(0,0){$y$}}
\end{picture}
