Using as.polynomial() over a matrix
...to be made into a polynomial in the equivalent row of (m_p). I have tried a coupe of things: ------------------------------ 1. Using apply() m_p<-apply(m, 2, as.polynomial) Here is what happens.. > dim(m) [1] 40962 3 > m_p<-apply(m, 2, as.polynomial) > m_p[1:5,] dM_I dM_a.c dM_a.c.sq [1,] -0.00593058 -0.000688 3.65e-05 [2,] -0.01913294 0.000103 1.41e-04 [3,] -0.01317958 -0.001190 1.49e-04 [4,] -0.02651112 -0.001550 2.37e-04 [5,] -0.01680289 -0.003520 2.86e-04 So - looks like the coercion hasn't worked. BUT, if I do things piecemeal - it looks ok.....
