Thanks a lot, it was very helpful, I did something like that:
EV <- ifelse(sprd > mediaSDP & sprd_d <= mediaSDP_d, -1, 0) SV <- ifelse(sprd > media & sprd_d <= media_d, -17, 0) EC <- ifelse(sprd < mediaSDN & sprd_d >= mediaSDN_d,1,0) SC <- ifelse(sprd < media & sprd_d >= media_d,17,0) in order to have 4 vectors and work with them.
