Hellos I have a rules-class element which I got from the apriori function in
the arules package, no I would like to stay just with a subset of the rules.
Does anybody know how can I create an object which has only the subset
corresponding from some indices I give him. For example if I have the
followint rules-class object:

   lhs
rhs                                   support confidence      lift
1  {}                                  =>
{tarjetas_flagrancia.adquiriente2=} 0.9960369  0.9960369 1.0000000
2  {datafono.marca5=}                  =>
{tarjetas_flagrancia.adquiriente2=} 0.8049805  0.9984959 1.0024688
3  {Target=1}                          =>
{resultado_investig.pto_comp=N}     0.8134982  0.9991282 1.0427348
4  {Target=1}                          =>
{tarjetas_flagrancia.adquiriente2=} 0.8106589  0.9956411 0.9996026
5  {antecedentes.estado=1}             =>
{antecedentes.medio=4}              0.8420383  1.0000000 1.1392183
6  {antecedentes.estado=1}             =>
{tarjetas_flagrancia.adquiriente2=} 0.8382231  0.9954691 0.9994299
7  {antecedentes.factor_riesgo=17}     =>
{antecedentes.riesgo=1}             0.8507926  1.0000000 1.1750886
8  {antecedentes.riesgo=1}             =>
{antecedentes.factor_riesgo=17}     0.8507926  0.9997567 1.1750886
I would like my result to be the following rule-class object if I choose to
stay with the third and eigth rules

   lhs
rhs                                   support confidence      lift

3  {Target=1}                          =>
{resultado_investig.pto_comp=N}     0.8134982  0.9991282 1.0427348
8  {antecedentes.riesgo=1}             =>
{antecedentes.factor_riesgo=17}     0.8507926  0.9997567 1.1750886

Thank You
