Hello,
I'm trying to run constrOptim. It returns to me an error about the fact that
constraints arguments (ui and ci) are non compatibles:
> optout= constrOptim(startparams, f=ImpulseSS, grad=grImpulse, ui=UI, ci=CI,
> data=gexp[k,], t=t)
Error in ui %*% theta : non-conformable arguments
I would like to point out that I can calculate that product in the command line:
> UI %*% startparams
[,1]
[1,] 2.297217e+05
[2,] 1.699765e+05
[3,] 2.037806e+05
[4,] 6.535699e+00
[5,] 1.014253e+01
[6,] 4.215988e+00
[7,] -2.297217e+05
[8,] -1.699765e+05
[9,] -2.037806e+05
[10,] -6.535699e+00
[11,] -1.014253e+01
[12,] -4.215988e+00
In fact, dimensions of "UI" and "startparams" are compatible in terms of the
scalar product:
> dim(UI)
[1] 12 6
> dim(as.matrix(startparams))
[1] 6 1
Thanks in advance,
Stefano
