    I loaded the LARS package,and input: data(diabetes),load the embedded data

   then I found the varialbes are in this form:

    x.age,x.bmi......(10 of them),X2.age,X2.bmi....(64 of them)    When I input x,R gave me all 10 varialbes,and input X2,it gave me 64 variables,but if I input x.age,it returned nothing,I wonder how to affiliate those subvariable such as x.age,x.bmi to x,since I create a table,name the variable x.1,x,2 ,it came to nothing when I input x.   I have never seen this before,can someone give me some keyword ,so I can search online,thank you very much.
