Question for R gurus:

Here's a re-statement of the question to make it accessible to R gurus who may not be familiar with OPR computation.

I want to know if R can solve for the least-squares solution to the overdetermined system of linear equations [A][x] = [b], given the attached [A] and [b] files.

An equivalent question framed in the language of statistics would be: [A] is a table (in plaintext sparse format) of 17842 sets of values for 2696 independent variables, and b is a column of 17842 corresponding values for the dependent variable. Can R read the attached files and compute multiple linear regression?
