[R] legend at fixed distance form the bottom

[Christophe Genolini]

Thanks to answering me Gabor

I am not sur I understand : I had your line to my graph. Then I resize 
my graph but the legend is still moving. In "inset = c(0,1.1)",
1.1 means "110% of the y length of the plot region". So when the plot 
region change, the distance between the legend and the top axe is sitll 
110%, that means that the distance between the legend and the bottom axe 
is 10%...
