Quantile Regression for Longitudinal Data.

Hi,

I am trying to estimate a quantile regression using panel data. I am trying
to use the model that is described in Dr. Koenker's article. So I use the
code the that is posted in the following link:

I am trying to change the number quantiles being estimated.
I change the codes about w and taus ,as following
w=c(.01,.02,.03,.04,.05,.06,.07,.08,.09,.1,.11,.12,.13,.14,.15,.16,.17
,.18,.19,.2,.21,.22,.23,.24,.25,.26,.27,.28,.29,.3,.31,.32,.33,.34,.35
,.36,.37,.38,.39,.4,.41,.42,.43,.44,.45,.46,.47,.48,.49,.5,.49,.48,.47
,.46,.45,.44,.43,.42,.41,.4,.39,.38,.37,.36,.35,.34,.33,.32,.31,.3,.29
,.28,.27,.26,.25,.24,.23,.22,.21,.2,.19,.18,.17,.16,.15,.14,.13,.12,.11
,.1,.09,.08,.07,.06,.05,.04,.03,.02,.01)
,taus=(1:99)/100,lambda = 1

But I get error message: .local(x, pivot, ...) : Increase tmpmax
So I am wondering if I am doing something wrong or I mistake w's meaning.

Thanks
I really would appreciate some suggestions.
Best
