Hi there,

I write a simple function that could place text along a curve. Since I am not familiar with the operation of rotating graphical elements, e.g., text, rectangle, etc., I hope you could give suggestions or hints on how to improve it. Thanks in advance.

For this kind of operation you might want to use tikz. 

R has the ability to produce tikz directives and to insert raw tikz into a 'tikzDevice'.

If you search rseek.org for 'tikz' you will get plenty of good hits. 

The tikz/pgf manual has examples of flowing text, IIRC.

HTH,
