Hello all,
                  I am new to r programmeand need help. I want to do
multiple linear regression analysis. say, I have two matrix 'x' and 'y'. I
want, 'x' as my response variable and 'y' as predictor.
Each time one column of 'x' will be the response, say x[,1], then next x[,2]
and so on. And also I need to store the coefficients in a matrix form.
Please help me.




> x
     [,1] [,2] [,3] [,4]
[1,]   -1    0    0    0
[2,]    0   -1    0    0
[3,]    0    0   -1    0
[4,]    0    0    0   -1



> y
           [,1]         [,2]       [,3]      [,4]
[1,]  0.6748156  0.266461216 -0.6883143 2.1332456
[2,]  0.5668101  0.295578807  0.1743760 0.4730689
[3,] -2.9465207 -2.313246341 -0.6060058 0.6236515
[4,] -1.5882276  0.002852312 -1.3152300 0.9082773
