Hi all: How does one read in an mps file and store it in a matrix as is. I have pasted the format of the file. I have implemented an mps writer but would like to have the capability to read in an mps file as well and store it in a matrix with out using the 'linprog' routines in R. Is there are way to use read.table or scan on the file below. Your help will be greatly appreciated. -Dhiren NAME test.2005-08-02.Tue ROWS N obj L CPA E ass1 E ass2 E ass3 COLUMNS 982323.1 obj 7.12279694339023 CPA -0.300433084368706 ass1 1 982323.2 obj -8.41320485916529 CPA 0.603671897647387 ass1 1 982323.41 obj 0 CPA 0 ass1 1 982351.1 obj -21.4471176117659 CPA 1.80909823649563 ass2 1 982351.22 obj -32.9606785054072 CPA 3.23030611400710 ass2 1 982351.41 obj 0 CPA 0 ass2 1 982554.1 obj 1.66536080466821 CPA -0.107303781434894 ass3 1 982554.23 obj -1.07268986390231 CPA 0.100720627703143 ass3 1 982554.41 obj 0 CPA 0 ass3 1 RHS rhs ass1 1 rhs ass2 1 rhs ass3 1 ENDATA
