[R] Linear system

2005-05-25 Thread Jim Gustafsson

Dear R-help

I have a problem solving a linear system like

353a+45b+29c=79
45a+29b+3c=5
29a+3b+4c=8

Is there any way of doing this in R?

Best Regards
Jim

1,200.44 , to 1200.44

Dear R users,

I have just start working with R and would need some help.

If you have a matrix as:


   [,1][,2]   [,3]
[1,]   11   24   11
[2,]   16   29   16
[3,]215 2

and you want the position where you can find the maximum value, in this 
case row 2 and column 2.
How could you get the position?

The values in the matrix is likelihood function values, and  each row and 
column represent values from two parameters. So the idea is to seek which 
parameter values maximise the likelihood and therefore I need boot row and 
column position.

Regards Jim

Hi,
I have a problem.
I would like to put my SAS-code into R.
Could I do that, if yes, how?


Best regards
