getting the response (dependent) from formula?
I'm trying to build a vector (fitting systems of equations) and I'm having a
little trouble getting the response variables from a list of formulas...
bdgmodel <- lbdg ~ d1sqr + ld1 + lhg
hgmodel <- lhg ~ ht2 + lht + whc
inst <- ~ d1sqr + ld1 + ht2 + lht + whc
systemeq <- list( bdgmodel, hgmodel )
# manually generate the y matrix...
y <- cbind( matrix( lbdg ),
matrix( log(hg) ) )
I would like to replace the previous line with something...
