[Rprotobuf-yada] Some help wanted

                I'm using RProtobuf (on Debian Wheezy, R version 2.14.1 (2011-12-22), just downloaded RProtobuf).

I'm using this proto file:

message caudal{
        required uint32 id = 1;
        required string signo =2;
        optional string s_id =3;
message sector{
        required string nombre=1;
        required string nombre_abreviado=2;
        required string gerencia = 3;
        required uint32 activo=4;
        required string literal = 5;
        repeated caudal caudales = 6;
message explotacion{
        required string nombre =1;
        repeated sector sectores =2;

I'm putting data inside a proto from a data.frame that I read from CSV (by the way I suppose it's not the best option but nevertheless I try). But I'm not able to use correctly the add method (for adding a repeated message):

sectores <-new(explotacion,nombre="SB")

for(i in conjunto){
                sectorini <-new(sector,
                               gerencia = as.character(gerencias[i,]$GERENCIA),
                               activo = as.numeric(gerencias[i,]$codi),
                               literal = as.character(gerencias[i,]$LITERAL.FUNCI)

I get "Error in add(x, ...) : could not get FieldDescriptor for field"

Could you please help me to use that add function: "sectores$add("caudal",sectorini)"

Thank you
