Thanks you very much! The way plot(fit, main="main title", xlab="X-axis lable", ylab="y-axis label") seems to work quite well, I didn't notice that I could do this.
I have in fact one more problem with it : the fact is that I have three plots that are called by the function. I can specify my three titles by doing "main=c("title1","title2","title3")" whithout any problem. But proceeding this way to specify the axes' titles doesn't work anymore. How can I specify three differents pairs of titles for these axes?
