[R] quantile fixed effects with weights

[alessia matano]

Dear all,

I 'm implementing the koenker procedure for quantile fixed effects. I
would like also to apply weights to the procedure, so that to give
more weight to the observation that better represent my original
sample (much larger than it is possible to use in R). Do you know if
it is possible? How could I solve this problem?
Thank you
