Dearfriends,
   A question related with resale(). I have a dataset *a*  with three
variables *x,y,id*
 I want to do two different things:
1. rescale the combination of x and y into the new range --unit
square(0,1),that is, keep the shape of original plot;
2.rescale x and y into the new range (0,1) respectively,change the shape of
original plot ;
e.g. the orignial dataset
id<-c(1,2,3,4,5,6,7,8,9,10)
x<-rnorm(10)
y<-rnorm(10)
a<-data.frame(id=id,x=x,y=y)

Thanks very much!
