[R] drawing against a date

[herodote@oreka.com]

hy all

I wish to draw a graph against a date,
I have a set of date like this DD/MM/YYYY, corresponding to it a set of integer , i wish to draw on x side the dates (the space between the dates have to be constant, not based on the time between 2 dates but on the number of dates) and on y side the integers.

Do i have to make a tricky function under R ?

I've search the help for graphical functions but my poor english seems to make me missing the solution...

thks for your help
