 Dear All,
Can I use lm() to fit more than one response in
 single expression. e.g data is a matrix of these
variables
R1 R2 R3  X1 X2 X3
1 2 1 1 2 3

 Now i wnat to fit 
R1~X1
R2~X2
R3~X3

in turn, and I don't want to do it use loops

of couse it it easy to make it using loops,but the proceed  is very slow since the data is very big

Can't anybody give me some tips or help, my eamil: guoshicheng2005@yeah.net

Best wishes
Yours Alxe
