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 Felipe Parra [[alternative HTML version deleted]]
