I've tried grouping the real and imaginary parts as a single complex number, e.g.
> z1 <- complex(real=r1, imaginary=i1) Although complex variables are not allowed in lm, I can run regsubsets just fine: > z <- cbind(z1, z2, z3, ..., z10) > bestsubs <- regsubsets(z, y, nbest=1, nvmax=5, intercept=T, > method="exhaustive", names=dimnames(x)[2]) The problem is that the code is using only one coefficient for each "z" (probably for the amplitude), and not one for the real part and one for the imaginary part, as I'd like to. > coef(bestsubs,3) (Intercept) z1 z3 z4 -397.43425 -35.86687 202.20521 716.02103 Any suggestions?
