Reducing augmented matrices

Hi How does one tell R that one is using an augmented matrix as appose to an non-augmented matrix?
Explicitly creating an augmented matrix is unnecessary and awkward if the object is to solve a system of linear equations. See: ?solve HTH, Chuck
For instance, when I want to solve two equations in two unknowns, I will have to solve a 2 by 3 augmented matrix, however all I know to type into R is something like this; weights = c(1,2,3,4,5,6) (say) M1=matrix(weights,ncol=3). Does R correctly interpret me when I write the above code? Furthermore, how do I reduce this augmented matrix in R such that it will give me my two unknown variables? Thanks so much. -- View this message in context: http://n4.nabble.com/Reducing-augmented-matrices-tp1018223p1018223.html Sent from the R help mailing list archive at Nabble.com.
