Hi, Goncalo: did u use compounds as features when building rf? If so, some compounds are NOT randomly selected in splitting nodes, which might explain what you observed. But you need to provide more info for us to help you, like those parameters you used to build rf.
You can use varImpPlot to see what exactly compounds were used by setting n.var (see ?varImpPlot) or you can use nrow(YourTrainingX$importance) to get that number too. HTH, w.
