[R] Get inside a function the name of a variable called as argument?

[Julien Roux]

Hi list,
I created a function to plot my data:
plot_function(vector)
I want to write the name of the argument vector in the legend/title of 
the plot.
For example if I call:
 > plot_function(my_vector)
I want "my_vector" to be written in the legend or title and so retrieve 
the name of this object as a string.

Is it possible to achieve this?
Thanks a lot for your help
Julien
