thanks...

i do homework..  my professor said , to use slover function in excel.
but i used R , so i want to find same function.

question is " Max(x,y)  x*E(R.a) + y*E(R.b)" , and x+y=1, 
E(R.a) and E(R.b) is average of the special data..

special data is this
        -------------------------------
         Nippon Steel Corp 
        -------------------------------
                 E(R)            = 4.65752 
                 V(R)            = 99.05973 
                 sqrt(V(R))      = 9.95288 
        -------------------------------
         Chubu Electric  
        -------------------------------
                 E(R)            = 2.19316 
                 V(R)            = 40.42778 
                 sqrt(V(R))      = 6.35828 
        -------------------------------
         TDK Corporation 
        -------------------------------
                 E(R)            = 1.10754 
                 V(R)            = 24.24186 
                 sqrt(V(R))      = 4.92360
